As long as you don't trip any of the automated checks to see if you are using a fake name or get manually flagged as using a fake name. The automated stuff is pretty stupid at the moment thankfully, but it's not something you can do if you care about not getting your account closed.
They don't close your account, they just deny the name change IIRC. And judging by the states of some of the names on my list, you don't have much to worry about.
