Use Tradfri standalone + integrated in HA


I’m using;
Hue hub for my Hue + Tradfri lights.
CC2531 + external antenna for sensors.

The CC2531 can’t reach all the sensors and I need some routers.
My son has a standalone(not integrated in HA) Tradfri light + remote that he bought himself. He wants to keep using the remote for controlling the light. The light is about halfway between the CC2531 and the furthest sensort

The question ;
Can I connect the Tradfri light to my CC2531 and still keep the normal function with the remote independantly of Home Assistant?
