Yes, but that doesn't mean they'd win. There are a fair number of people who we categorize as citizens who the Constitution does not actually require us to categorize in that way, and that's pretty much a legislative privilege which the courts have deferred to. A law that made Schwarzenegger eligible might run into issues with being excessively retroactive (it's usually assumed that natural-born at a minimum requires being born as a citizen) but it's not otherwise beyond the powers of Congress.
