Whoa - Hold on a moment here - These are Li-Ion batteries and you'll be charging the AAA at around double it's normal rate.  Lithium Ion batteries don't like that and you may will destroy the battery and worst case have a fire to deal with in the process.

If you really want to try it, keep a Very Close Watch on it and disconnect immediately if it heats up or makes fizzing or popping noises.  Better safe than homeless!

Assuming the voltages are the same, then yes, it should work.
