But I would imagine the point of carrying the licence is that you have a photo i.d. so the Guard has confirmation that the name you are giving him is correct.
Otherwise there's nothing to stop you saying "I'm Timmy O'Donnell and I'll drop my licence into Lisdoonvarna Garda Station next Tuesday".
To use the earlier example, if you're going on holidays you wouldn't expect U.S. Immigration to believe you when you tell them your name if you have no passport to back it up.
Or would you?
