It's only possible if you have access to the primary device and use it to allow permissions for a secondary device (laptop or tablet usually).
But even having done that if the primary device user wasn't aware then all they'd have to do is enter Settings>>>Linked Devices and they'd see what other devices are connected to the WhatsApp account at any time, and would be able to instantly disconnect it.
