From my experiences with greyhound, they usually don't mind a skateboard/snowboard if there is plenty of space in the cargo hold. This also applies to luggage exceeding usually allowed size.

I think these rules are very dependent on the bus terminal and the line.
First, Vancouver-Calgary is a part of the transcontinental line. So a lot of people are moving with a lot of stuff. From the little I saw, they are cool with everyone bringing random things such as guitars and even a bicycle, but I would not say it's always the case.
For the terminal, I remember they were nice in Toronto, not even checking the number of bags. In Calgary, however, they charged 10 bucks for each extra or oversized bag.
Know that they also have a shipping service in Canada, so they make money out of this.
All that said, I would recommend you to directly go to the terminal and ask about their policies, to know if it is cheaper to buy a snowboard bag or pay a fee or if you are just lucky.
