No, by default the VM does not define an icon. On modern Linux desktops, window icons are not specified by the executable anymore. Instead, the desktop comes with a "theme" of colorful icons. Typically a "desktop entry" file is used to associate applications with icons. See
http://standards.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.htmland ask your favorite distro packager for how they handle icons.
There still is some window icon support in the VM, but it has been unused for years. I found this in an old file - try putting the following into platforms/unix/vm-display-X11/squeakIcon.bitmap and undefine NO_ICON in sqUnixX11.c:
#define sqXIcon_width 32
#define sqXIcon_height 32
static char sqXIcon_bits[] = {
0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x30,0x00,0x00,0x0c,0x48,0x00,0x00,

Recompiling should add an old-fashioned black-and-white icon to the window. But it's quite possible that modern window managers ignore this.
