Can You Rename M4V to MP4?

Can I change MP4 format to M4V manually by just changing the extension on Mac or Windows? I need to change an .mp4 (h264, AAC) to .m4v. Can I just rename it from x.mp4 to x.m4v. By renaming, I mean clicking on it in Finder on Mac or Explorer on Windows.

Many users are wondering if they can just manually change the extension .mp4 to .m4v without using converters. MP4 vs M4V, they are exact the same, so you can manually change the file extension between .mp4 and m4v, and file are still playable. When you play these files on PC, remember to switch it back. However, only the file extension changes, not the codec. If the original MP4 is not playable on Apple devices due to codec incompatibility, this method won't help.
