Only if you are stupid enough to tell them. And even then, that would not survive in court. If you just no-show for the last flight, nothing happens.
Of course, since you only have 1h in ZRH, this means that you can't have checked bags since those would be checked through to WAW (no check-in agent will short-check bags to ZRH if your stop there is 1h).
