No - the remotes don't know they're paired, only the devices.
My theory on this is that each remote has an identifier code transmitted with the IR instruction.
When a device is paired it only responds to a remote with that identifier and ignores others - so unless the iMac was paired with another remote it would still respond to the one AppleTV was paired to.
