It's quite possible. That's not to say it will happen, but if you are really worried about losing the neons, you may want to think about a larger-bodied tetra. How big is the angel right now?
It is somewhat of a balancing act when choosing a tetra for an angel tank. I've had problems with black skirts and serpaes nipping at my angels' fins, and would not recommend them.
