Can undervoltage damage electronics?

If an electronic device receives lower-than-expected voltage due to a malfuntioning psu or dying battery, can this damage the device permanently?

I ask this because the battery in my surface pro pen was on its last leg (it was 0.4v instead of the required 1.5v). I thought it was the battery. I replaced it with a new one. Nothing. Pen is dead.

Now I'm worried can this affect other battery-powered electronics if it were poorly designed? Overvoltage can, but not sure about undervoltage.
 
Well I would argue that there's a difference in undervolting and dead battery... undervolting an already overcloaked GPU... no problem at all ! Dying PSU on a GPU, big problem...
