What Aqua said. Newer lore trumps older lore, not game lore trumps book lore.
And besides, that means 2 things: the original orcish word for dragon means something else and it was translated into Common wrong, or we're wrong and they weren't established until they found out about dragons. And since we've already proved the latter wrong, it means that it was translated wrong or something else.
The lore explanation is that the Orcs didn't have a specific name for the world at all (they just called it "the world"), since they didn't really have any knowledge of any other worlds. As they began to interact more directly with other worlds, they ended up adopting the Draenei name for the planet (Draenor) since that was the only one they knew.
The meta-game explanation is actually the opposite of this. The Draenei were actually named after the world itself, which at the time made perfect sense because they were originally supposed to be natives who had lived alongside the Orcs (until the Orcs killed most of them). It wasn't until the Burning Crusade that their backstory was expanded to include them arriving from elsewhere.
Roleplaying, hardcore Raiding, running LFR on the occasional weekend, PvPing, rolling alts, achievement hunting, pet battling, or just enacting an endless series of whims, I don't care how you play WoW. Just as long as you have fun doing it.
“We fell in love with this land, and we call it Draenor.”
Durotan nodded. He had heard the term before. He liked how it sat on his tongue when he spoke it, and the orcs did not have a name for this place other than “world.”
“It is our term, we have not the arrogance to think the orcs would use it as well. But such we have dubbed it, and we love Draenor deeply. It is a beautiful world, and we have seen many.”
--Rise of the Horde
Draenei giving the name to Draenor was also in Beyond the Dark Portal (2008).
