On the endof10.org website, they have various vendor logos, and a page of places people can go to upgrade to Linux.
It would be good to have a list on there of operating systems people can install (because if they need the endof10 website they probably need to be given the options).
So yes, I think Fedora should support endof10. I note that the website is hosted by KDE and has a number of other good orgs behind it.
