If the tree is not currently infested with beetles... you have little to worry about. They don't tend to attack dead wood after the fact. If the tree is still up and you can get it taken down before spring emergence- do it. Though they can overwinter in bark, they like to emerge for spring feeding on tender new bark. Taking the tree down while still dormant can help reduce that risk. And if you do have an infestation, you can spray the tree with insecticide- follow the instructions on the label.

Fortunately, a ten foot tall sapling isn't likely to be mature enough to be very attratctive to the beetle unless you are in a very infested area.

I wouldn't worry about it. There are going to be dead elms around you somewhere -- there are dead elms all the time around my area in forest and roadside edges. so I seriously doubt your one tiny 10 ft elm is going to make any difference.
