Yes, you simply rename the file to have a ".php" extension.

It's possible, yes (such as forcing all .html files to also be passed through the PHP interpeter, mod_rewrite, etc.), but does it really matter? What's wrong with simply renaming the file to have a ".php" extension to properly reflect how it should be handled by the webserver?
