It's not even necessarily about "younger".
Consider the scenario where you have a new account, and a character in it showing up in a realm saying, "Hi, I'm back! Remember me? I was your Judge 4 years ago!" when the account clearly states that it has existed for less time than that, and the character has clearly never been Judge of the realm.
This is a case of the player claiming one thing, and the game claiming something else. As usual, when in doubt, the game wins.
