Whether or not you can practice it is up to the campus or whoever owns the property where you are. It's their property; if they give you permission, you may. If they don't, you may not.
Be prepared for them to tell you "no." If they say "yes," and you hurt yourself doing it, then they may be liable for your injuries and medical bills. It falls into kind of the same area (and reasoning) as skateboarding.
