Can you use a 20v battery in a 40V tool?

No, not without intervening circuitry to step down the voltage to 20 volts. You can generally use a higher capacity battery (that is one with more amp hours and thus run time) but the battery itself has to be 20 volts. Higher voltages will destroy the tool. via

Does 40V battery last longer than 20v?

This means that the 40V trimmer will operate for a little over three times as long on a single charge, as the smaller 20V unit. Simply put – more watt hours = more “fuel” and longer run times. via
