That's one way of looking at it, but I think it's more complicated than that. The way I see it, anything that anyone can create, that exists independently of creator and user in a physical form, and used by someone who isn't the creator, can probably be termed "technology". Meanwhile, things that rely on some sort of innate gift or learned skill the creator has in order to continue being could probably be determined to be "magic".

That's a very simplified view, of course, but it's a good starting point.
