    The LED is at pin 13 and it glows only when the stopwatch starts, and stops glowing when the stopwatch stops..

    you can use any LED for the job..

    yes it will work without the led, as you are using Arduino and it has a on board led at pin 13 so no change in the code will be required.. it would work just fine..
