Well, in reality, no, a grenade launcher fires a grenade ballistically, like a firearm's cartridge, while a rocket launcher fires a grenade that keeps propelling as it's launched in the air, by the use of solid fuels, and typically carries a heavy payload intended to penetrate armor, generally tanks, thus using a shaped charge, that directs and focuses an explosion to provide absolute maximum penetration.

You could conceivably make a weapon that uses a multipurpose grenade that can do both, but this would actually just be shit and it'd suck at one or the other, or both. It's for convenience of gameplay and simplicity that Quake launchers use the same ammo pool for both, because realism isn't really that relevant to a game like Quake.
