Answers.Text: As far as I know, there is exactly _one way_ for the player who can't checkmate anymore to still win -- if the player who can still checkmate _resigns_ (see https://chess.stackexchange.com/questions/9312/can-i-resign-if-my-opponent-only-has-his-king ). Other than that, even if the stronger side forfeits for using their phone or so, it'd still be 1/2 - 0 instead of a win.

Answers.Text: @RemcoGerlich: How about a team match with fixed ranking numbers which were botched by the team captain, or a player that hasn't an allowance? (OK, technically, both cases still count as win for ELO computation, but list as lose for the tournament, if I recall correctly.)
