Yes. Basically that's what mount -o loop does internally before mounting it to 
a filesystem; you just have to set up the loop device separately.

For info on that, do a man losetup, basically what you need is:

losetup /dev/loop0 myimage.iso

and tell VMWare to use that loop device as a CD-ROM block device.

YMMV though, as a true CD-ROM block device supports IOCTLs which the loop 
device can't/doesn't.
