Checking Region images without automatically having Checkpoint ticks and crosses in test log

I'm assuming there is actually a child object called "imgCoil" on icon?  You might want to double check that.  That's part of the problem.  Depending upon the timing of things, that object may not exist when you call your code.

As for the other half, you need to change your code to the following:

def new_image_check(self, icon=None):
   if icon is None:
      icon = self.frmMain.frmStatusBar.pnlPIFs.framePIF_right
   if not Regions.Compare("imgCoilCon", icon.imgCoil, False, False, True, 0, lmMessage):
      return False
   return True

If you're going to use an item in your Regions collection, the parameter for that is a string that is the name of the Regions object that you want to use.
