I would be surprised if any airline just let somebody on board with only a boarding pass/seat assignment for another flight-- but it may happen, perhaps.

HA does, at least for intra-island flights. They have a "Standby Line," and basically they count seats and start boarding from this line of people and take essentially whatever travel document you have.
