In Stormwind, at least, the battlemasters (i.e. the NPCs that will queue you for battlegrounds) never attack Onyxia's dragonkin, so I'm assuming combat with NPCs is not possible (under normal circumstances). I wonder if they can be engaged by Horde? I've not yet made it Horde side to try this out myself...
Lazy Battlemasters! But I assume this is so that BG queues are uninterrupted. There's also the possibility that this was not always the case in Vanilla I suppose.

They do attack horde players, however they are just scripted not to interact with quest mobs such as the onyxia attunement chain.
