The answer is 'YES'
Create an OS volume snapshot same as source OS volume, you can present it to another host as a bootable volumes.
As I know, Other EMC storage like VNX , VMAX are all supported in this way.

I guess my concen is that as a snapshot it would still have pointers back to the original volume.I am more accustom to clones that are independent volumes.

Both Snapshot (with Pointer) and physical Clone are block level LUN replication, the target LUN should be identical with the source LUN. To make it bootable to the target host, you may need to perform certain steps on both the server and the SAN storage sides
The following guidelines should be followed for host connectivity to SAN environments (take Linux for example):
Basic boot from SAN procedure:
