RT: Definitely no
Pro. Kinda tricky. There will be no drivers for touch screen probably. I don't know if keyboard works on simple USB. Plus, there probably won't be motherboard support, which would kill battery life. Oh. Surface uses UEFI. Mac OS X also uses UEFI. But Surface UEFI is lockdown, so it would be hard to trick Mac OS X into thinking that Surface is a Mac. In addition, installing Mac OS X in most cases is illegal. (Unless you are an Apple Engineer). Simple answer is no.
We will try next time™
