Teleportation is teleportation of matter. So AFAIK you can't call it quantum teleportation, for the same reason you can't call travelling along the road "road flying," i.e., flying is travelling above the ground, not on it.

The human ability to generalize concepts is amazing, watch—I'll swap out your of matter for of quantum information and suddenly you're up to speed on subject of discourse: "The teleportation of quantum information." Magic!
Your language gives you away, you've already done this process in reverse to make your case, so I know you have the power to understand this concept.

So we can use any word to mean anything?
This kind of abuse of language has serious consequences in the long run. The language of modern physics is already way too muddled.
I don't understand what you're trying to say in the last sentence. But it seems like you're being derisive, which is utterly inappropriate.
The quantum state does not undergo travel during the transmission of the classical signal. The only thing that travels is the classical signal, which is needed to tell you how to read the message (and generally preserve causality in the universe.) The quantum state is teleported as though you had two objects with the selfsame quantum state. Poking one pokes the other.
