There are no legal challenges and there is no hurry. You wouldn't be able to call the fork Fedora but other than that it's absolutely impossible for any shady backroom deal to affect your future ability of forking Fedora. The licensing of the collection as well as the individual components grants you that right and there is no way to take it back retroactively.

With the current state of things, forking Fedora seems unlikely to be a wise decision. RedHat is the major contributor, paying the salaries of many Fedora developers. So far, nothing has changed here with that acquisition.
