I know I didn't take the front wheel off to remove the fender. I do remember it was a squeeze though because of the way the fender slightly bulges around the legs, so you do risk scuffing it if you're not careful. It's just 4 bolts (10mm heads maybe?) and the cable holders you gotta release, then "roll" the fender around to the front of the wheel and pull it off. Since the bolts are on the inside edge of the legs you may choose to approach them from the back side, relative to the bolts, so make sure you get it straight in your head which way to turn them.
