I'm not a EULA wizard, so I can't decipher the language any better than you. Take my post with a grain of salt. But there is a difference between "unsupported" and "disallowed".
From the snippet you posted, it sounds just unsupported. Tech support will not answer any questions on it, you will not get bug fixes for free, etc. If it works, you can to do it.
Boot camp is unsupported by Apple, all that means it you cannot ask people at the Genius bar to help you set it up and fix any problems that happen.
There's no limitation keeping you from running it, unless you refuse to run unsupported configurations. This is the case for many business environments which would not be running the home SKU anyways.
