Probably not if done gently, but not by "Bang" ing" as you ask in your other post. It can probably be pushed back out by your thumbs if you start at the edge of the dent and work your way to the center. A rubber mallet and light taps would be a better tool to use than any other kind of hammer. Basically, or to put it bluntly, if you know what you are doing, you can get the dent out without damaging the chrome.
