Sure it is. Each separate WPA connection involves a unique nonce (actually four, IIRC); my laptop and your laptop aren't using the same key even if we sign in with the same password. (This gets to the problem that WPA is being used for access control, which is not what it's actually "for", but that's a separate question.)

If you are sniffing the 802.11 frames (and you should assume someone is) and you catch the entire 4-way handshake and the nonce generation is predictable you could reverse-engineer it, but then again you can say the same thing about a TLS connection too.
