    Would it cause any harm to connect a 24 volt motor to a 12 volt
    battery in order to see if the brushes and everything are ok? I know
    it will run slow but could it harm the motor in any way to try it for
    a few seconds?

    try it for a few seconds?

    Overheating is the enemy. A few seconds won't hurt anything.

    I wouldnt have thaught underpowering an electric motor would overheat
    anything ? does it generate more heat than applying the full voltage ?

    The motor will overheat quickly when it stalls.
    Two ways to achieve a stall are excessive load at normal voltage or
    normal load at low voltage.

    The problem would come if the motor didn't have enough oomph to rotate.
    A motor which is mechanically stalled is the worst-case condition.
