That would involve jailbraking. The nice thing about the M series Macs is that there is an offical way to run alternative OSs, AFAIK. Something that should be required by law after X number of units sold IMO, but that's another conversation altogether.

To give credit where it is due, I remember one member from the project mentioning that Apple actually did quite stellar work to enable other OSs while still maintaining a secure booting mechanism (for both osx and future third party ones!)
