1) You are still too far far from the bubble for ICM to have that much impact. In general ICM starts creeping up once you reach spots paid + 50%. So here ICM will start becoming a smaller factor at 18 players. Then at spots paid + 15% it sort of hits a spike. So the ICM spike is around 14 payers. Of course, ICM is always a factor, but it is on the smaller side still with 21 left and 12 paid.
2) So now we resort to a pot odds scenario. Your pot odds give you an break even equity of 33%. But you should not call off at break even here. There is some ICM. I would add another 5% here and call off with 38% equity.
3) When you do a home analysis, you should not rely on a single range. I always use as a middle ground the most likely scenario. But additionally, consider if he is tighter or looser than your expectations. You have to run those as well and compare the results. Sometimes, even the worst case will still end up being a close call. Sometimes you may see the worst case being an easy fold, and the middle case and best case might only be marginal calls. In that case, it might make sense to play cautious and fold.
4) You cannot exclude a bluffing range from the analysis. That is an error everyone has made in the ranging of the players above. The Dan Harrington rule: Everybody bluffs! When ever someone make a big bet in the pot there is at least a 10% chance it is a bluff. When I choose bluffs for my range I will try to choose the bluffs that are a little worse for us. Here instead of choosing A5s (a favorite bluffing hand of many players, I will choose some suited connector type that is not dominated)
Here with 7 players, the 4 bet range should be a balanced range about 3% in total.
Standard case:

UTG 57.77% { QQ+, AKs, 98s, AKo }
BU 42.23% { AKo }
Worst case: His value range is a bit tighter and I will remove his bluff. ( I would usually set this at the 10% minimum, but his value range is so tight, 1 hand won't spoil the results that much).

UTG 62.98% { KK+, AKs, AKo }
BU 37.02% { AKo }
Best case: His value range is a slightly wider and add an extra bluff:

UTG 55.71% { JJ+, AKs, 98s, 87s, AKo }
BU 44.29% { AKo }
What we see from these numbers is even the worst case scenario is only slightly worse for us than the 38% padded equity. It is still more than the real break-even number of 33%. While the standard case and the best case are good for us. With all of this information this has to be a call here.
