There's no reason they couldn't add a full secure enclave on a USB based keyboard with TouchID.

Register your fingerprints into TouchID, they are stored securely on the keyboard, with some secure communication between keyboard/computer... now you can easily log in and or do Apple pay.

I agree. However I think they'd lean towards devices that already have such tech rather than creating another one.

Now when happens when I unplug the keyboard and plug it into something else?

Nothing. Since there is no relationship between the secure enclave on the keyboard and the laptop, TouchID won't function.
