With premium bullets, I know that people have taken coyotes with the 22WM, but not NEARLY as many as with the .22 caliber centerfires. Even then, you need to be pretty darn close to shoot, and kill, a coyote with the 22WM.
As for hogs, I had an uncle that once killed a 200 pound hog with a .22LF and it dropped right in it's tracks. How? Well, the hog was about 15 yards away, and it was shot right in the head between its eyes. Still, I would never advocate using a .22LF or even .22WM for hogs - there's just way too much margin for error.
