Yes, you could;
Also, a check-in agent could confirm the changes but as I've mentioned in the first post, if you wait until check-in, you may lose your seat assignments or you might be dumped off from a flight due to overbooking.
If you ask the load for your flight here, 2 days ago, I could give an estimate about the flight being overbooked or not.
