Techncally no.
This also refers to people who were baptized into the Catholic Church as infants and were brought up outside of the Faith or left. There is a thread on Catholic Answers about a woman who is eastern rite yet left the Church and married a non Catholic and wants to return and there are complications. In another case someone who was baptized in the Catholic Church, was brought up outside the Church, married outside the Church, came back and at RCIA her sponser told her she was "living in sin."
There have been other similar situations. In each of these cases they had to be married in the Catholic Church as part of their return to the Faith.
