ELI5: On a lower gravity planet, would it be possible to jump high enough that you could injure yourself when you land? Or would it be impossible for the impact to be that severe?

Assuming no atmosphere, the force it takes to launch from the surface would be equal to the force of collision with the surface upon landing.  So the gravity of the planet doesn't matter - the question of whether you can injure yourself is dependent solely on the force you can exert with your legs.
