Why convert M4A to WAV?
WAV is uncompressed, so further editing and re-saving won't reduce quality any more. (It can't restore detail that M4A compression already removed.)
WAV is best for audio editing, DAWs, mastering, broadcast and archiving. Supported by every audio editor, DAW and operating system.
Will I lose quality?
Converting M4A to WAV keeps all the quality that is in your M4A file - nothing more is lost. However, it cannot recover detail removed when the M4A was originally created, and the WAV file will be larger.
