Give them some root boost and they may survive but corn does not like being transplanted and may sit and pout for awhile.

Corn seeds germinate rapidly directly in soil. For good polination, corn is usually planted in a rectangle. Therefore, direct seeding of more plants than you may have would likely overtake the transplants and do better with more corn.

I've done that a thousand times. It will be fine as long as you keep it moist for a couple of days.
