The easiest solution is to put a queen excluder on. The drone brood will mature and they can use the cells for honey. You are probably correct the queen is moving up for a reason like a healthy hive. When there is no room to lay brood they are honey bound. It would not be a concern near Winter time, but they still need room this early. Honey bound is like asking when a truck is overloaded. If it is driving down the road safely - it is perfectly loaded. When you cannot stop or turn without rolling the truck or load it is overloaded. Too much depends on a bunch of factors. If you have to ask yourself if you need to inspect the whole hive, you probably should have already done so.
