Veral used to make some 41 molds with a shank cut for the 416 check, and I offer 41 molds cut either way. There is a difference in the shank size, 0.3975" for the Lyman and 0.393" for the Hornady 416, so you are going to be shaving lead if you try to force the 416 check onto a bullet that was cut for the Lyman 41 check.
