The icon is baked into the VM executable.  So to change it one has to build
a VM with a different icon.

On Windows it is in
    {build.win32x86,build.win64x64}/pharo.cog.spur/Pharo.ico
and the file that specifies to use Pharo.ico is
    {build.win32x86,build.win64x64}/pharo.cog.spur/Pharo.rc

On Mac OS X it is in
    platforms/iOS/vm/OSX/Pharo.icns
(alongside three others such as PharoImage.icns)
and the file that specifies to use Pharo.icns is
    {build.macos32x86,build.macos64x64}/pharo.cog.spur/Makefile
in setting the VM variable.  The file that associates the other icons with
specific file types is
    platforms/iOS//vm/OSX/Pharo-Info.plist

If you're changing the Pharo icon let me suggest you update the icon files
themselves in the opensmalltalk-vm source tree.

If you're creating a new variant of the VM for some new purpose (say a
special Lam VM) then let me suggest you add the icons to the
opensmalltalk-vm source tree, creating special build directories for these
VMs, such as {build.macos32x86,build.macos64x64}/lam.pharo.cog.spur/

If you want to do this privately, then take either of the approaches above
and simply don't publish the edits.  You can write a script that takes an
updated checked-out opensmalltalk-vm source tree and edits it with files
from a specific repository.  I have such scripts and can help you with
them.  Hint, pax is a very convenient directory hierarchy copying tool
available at least on Mac OS X.  pax -rwlk will copy the trees under a
sequence of directories into their corresponding places in a target tree.
