As long as it was not used on the ceiling (there are different framing requirements for green board when installed on the ceiling) about the only difference you may see may be in the finished wall as the paint may show differently on the different paper of the green board.
Green board is not suitable for use where Type X is required, but I doubt there were any areas which required Type X in the stairway or the living room.
