No. You add friends by going into GameCenter and inviting a friend or accepting an invite that someone has sent to you. Your real name will be sent to them as well, but they won't be able to see anything else on your phone. You will not be able to send messages to them unless they are in your contacts list. In other words, if all you know is their GameCenter name, then once they accept your friend invite you will not be able to get any additional information about them other than the name they call themselves on their iPhone.
