[Harry Potter] Was it possible for Harry to die while he was the unknown Horcrux?

If he had fallen off his broomstick or been hit by a bus and died in a less dramatic way would he be able to come back like he did at the end of Deathly Hallows? Or was it only Voldemort hitting him with another killing curse that killed just the Horcrux in him but left Harry able to come back? When he has the meeting with Dumbledore inside his head he’s seemingly given the opportunity to go “on” but he makes the decision to go back. As long as he had the Horcrux inside him could he always do this?

Yes, until the end of his fourth year at Hogwarts. Once Voldemort made his new body out of Harry's blood, he reinforced their bond and the protection on Harry. Voldemort could touch Harry, attack him... but he accidentally bound Harry to life as long as he himself lived. And as Voldemort was immortal, so too was Harry Potter, until Harry surrendered himself in the Forbidden Forest.

After the fourth book, yes. He could be injured, but he would always be just barely clinging on to life, no matter how severe the injury, because Voldemort still lived. Some quick magic to repair his body and he would be fine. 

Before the fourth book, no. Unless Voldemort or one of his minions was driving the bus, in which case it would probably crumple when it hit him.
