Globally, no. There's simply far too many Christians across too many cultures to say there's a single Christian lifestyle outside of the major faith based doctrines and holidays.
On smaller scales, yes, there's interesting commonalities in lifestyle decisions. In parts of the USA, for example, a large swath of Christians also share many interests that a large portion of the rest of the population does not. Things like politics, sports, entertainment, pastimes, and secular music conflate heavily as "Christian" things. It should be noted, however, that it is unlikely that the religion affects the culture, or at least, it affects the culture less than the culture affects the religion. In other words, most of these secular values would likely exist without the religion present.
In other parts of the world, a similar phenomenon exists. A good example is the syncretism in Mexican/Latin Catholicism. I've never researched it, but I suspect the phenomenon can be found in Islam as well, and perhaps in Hinduism and Buddhism. The typical sociological understanding is that religion is a part of culture, and reflects that culture. If religion is present, it cannot be divorced from the culture where it resides.
I attribute this difference between Judaism and Christianity to two things: numbers and xenophobia. There are 1.5 billion Christians and only 20 million Jews. You simply can't compare them. Judaism is also marked unique because of its intense and inherent resistance to syncretism, which some describe as xenophobic. Conversely, Christianity has many instances of syncretism throughout the ages. The interesting question is if Judaism could maintain its strict cultural mores if it also had a billion adherents.

Is it possible to describe Christian lifestyle, values, and practices without emphasis on faith? If not, why not?
No, because our Lord Jesus Christ said (John 15, 5-6):
I am the vine, you are the branches. He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing. If anyone does not abide in Me, he is cast out as a branch and is withered; and they gather them and throw them into the fire, and they are burned."
and saint Paul the Apostle explained (Romans 4, 1-8; 5, 1-2)
What then shall we say that Abraham our father has found according to the flesh? For if Abraham was justified by works, he has something to boast about, but not before God. For what does the Scripture say? «Abraham believed God, and it was accounted to him for righteousness.» Now to him who works, the wages are not counted as grace but as debt. But to him who does not work but believes on Him who justifies the ungodly, his faith is accounted for righteousness, just as David also describes the blessedness of the man to whom God imputes righteousness apart from works: «Blessed are those whose lawless deeds are forgiven, and whose sins are covered; blessed is the man to whom the LORD shall not impute sin.»
... Therefore, having been justified by faith, we have peace with God through our Lord Jesus Christ, through whom also we have access by faith into this grace in which we stand, and rejoice in hope of the glory of God.

Given that there are over 2 billion Christians and only 14 million Jews, there is considerably more diversity in Christian lifestyle and practice compared to Jewish lifestyle. That said, the Wikipedia article on Christianity summarizes the commonalities that most Christians practice in their life, which identify them as Christian.
There are certain exceptions to these traits (e.g. New England Puritans considered themselves Christian, but did not celebrate Christmas). However, I would say that the vast majority of active Christians would follow these aspects in their lifestyle, thus it can broadly be considered a "Christian" lifestyle.
