Yes and no: The tramway does not go to the airport, but the Al Bidaoui regional rail does, connecting it to Casa-Voyageurs station:
The train station is situated at level -1 in the arrivals area of Terminal 1. Trains depart from the airport to Casablanca or viceversa every hour between 03:00h to 22:00 approximately. Journey time is about half an hour and the ticket costs 30 MAD (around 3 USD).

The map you linked to is a plan for 2030 showing current and future lines for both tram and train ("R"). A map of actual extent of the current tram system is available on the tram's official website.

There is no tram, but the train is easy to navigate for a foreigner. You can withdraw cash from your foreign credit card in the airport terminal and pay in cash.
With basic French, you can check the timetable at http://www.oncf.ma/Pages/Horaires.aspx - search for trains from AEROPORT Med V - CASA VOYAGEURS
Trains are (currently) hourly, and thereβs only one line so you canβt go wrong.
