Yes and no. One Opener does not support to control another Opener independent of a connection between the two.
If you want to remote control a Nuki device you can do this directly via BLE with Nuki Accessories (Fob, Keypad) or the Nuki App or you use one of the integrations that use the Bridge or Web API.
The Fob is paired directly to an actuator (Smart Lock or Opener) and communicates via BLE with it.
If it can be operated by closing a contact (up to 50V/2A), it should work.
