In a paid game the immediate question would be what are the payout structure, because it can condition marginal calls into folds if it is relevant to have more chances to finish 2nd.
Second it's a matter of read about how tight is UTG, but AQo is part of top 5%, so it would have to be very tight to make this unprofitable call.
In a winner take all scenario, assuming nothing special about UTG the nash equilibrium calling ranges are 44+ A8s+ ATo+ KQs, making overall AQo a fairly easy call. It's closer for a 50/30/20 payout structure but still a call with 55+ ATs+ AJo+.
It could be that you are being sightly result oriented by the fact UTG has JJ to estimate his range, but UTG actually can profitably push with ATo, KJo, A8s, 22, etc.
