I think that yes. In Mac OS, what you have to do is:

1) Go to your vm� (for example Squeak 4.2.2beta1U.app), and copy it (backup) with another name in case you don't like the icons
2) Go to the original VM ->� right button -> Show package content
3) Check in the directory /Contents/Resources/ and you will notice all the icons that are used for spicifics files: the .image, .changes, etc. You can select your owns, put exactly the same file name and override them.
4) A reboot may help to see all the changes
