23mm is 23mm and somewhat larger than a 20mm, so the answer is no, you can't.
The F-86F-2 was not a success in Korea and most were reconverted to standard F-86F standards later. The Navy was first to get a 20mm Sabre out there, but as the FJ-2 Fury. None of them served during the war, and the later F-86H with 20mm guns did not enter service until late 1954-early 1955.
Also explosive .50 caliber ammunition was also a cropper, with at least two F-86s being lost in Korea due to explosive bullets blowing up in their magazines and crippling the fighters. (operational losses, not air-to-air.)
