That would be a violation of the copyright law or the GPL licence - you aren't permitted to take GPL code and redistribute it with some extra restrictions added on to it.

If it's not (fully) your code, you aren't free to set the licence conditions; Linus can't do that without getting approval from 100% (not 99% or so) of authors who contributed code.

What one can do is add an informative disclaimer saying "To the best of our knowledge, installing or running this thing in California is prohibited - we permit to do whatever you want with it, but how you'll comply with that law is your business".
