Kind of, but it's not the way to do it. Imagine you've got a cup full of water and an empty cup of water. If you put them together, you'll have two cups half full of water, but still have only the same amount of water. The same thing will happen with the batteries -- you'll end up with one emptier and the other one fuller but still have the same amount of energy combined (actually slightly less as charging isn't 100% efficient).
