He can't ignore orders from Yelena since he is the leader, though I do think it was a bit reckless to charge in like that. However, as we've seen of him so far, while just as bold, he's also much more thoughtful than before so it's possible he had a reason to attack. Maybe he was afraid Marley would take over the buiding where the prisoners were being kept, as it was insinuated that Eren still cares about his former friends; his motives and reasons haven't been entirely revealed yet after all. He would've left his comrades even more vulnerable had he listened to Yelena and left the scene, for there was no way the soldiers alone would've been able to deal with both three Titans and the MArleyans attacking from high and low, at least not without tremendous loss of life.

There is also some possibility that Eren is giving his all because he has a child with Historia.
