Not advisable !
You will create heat-tension to the glass of your lens.
Some camera's, like the Leica's have an infinity-focus-lock: a pin that you have to push in in order to be able to focus.
If this camera has not such a lock some penetrating oil can help, but remove the front ring first !
The front ring is helt into place with 3 tiny screws.
After the penetrating oil has done it's work you should be able to remove the lens part, use a pair of suitable pliers if nec.
Clean and relube.
Next is to set-up proper focus again: put of ground glass in the film gate, open the shutter at the B-setting and focus at infinity and than replace the ring with the 3 tiny screws. Recheck.
Good luck !
