Unfortunately, no. The black Apple TVs use a similar restore function as the newer iPhones (3GS and up). They are device specific so using another's device to clone is not possible. As part of the restore function, Apple is pinged to check to see if a specific device can be restored to a specific firmware. Once a new firmware comes out, Apple stops allowing older firmwares to be installed. Your only choice is to get the new firmware.
One can save a device's SHSH files (also called blobs) which are a device's signature file which includes the device's info and the specific firmware using a tool called TinyUmbrella. If one has their blob for their device and a specific firmware, it is apparently possible to roll back to an older firmware using TinyUmbrella. It acts as a middleman and provides the necessary approval for a firmware to be installed on a specific device, sidestepping Apple's approval. The issue is that once Apple stops signing SHSH files for a firmware, there is no way to get it.
I say it is 'apparently possible to roll back' because I have not been able to do it with my Apple TV. I have done it successfully with iPhones but I must be doing something wrong with my Apple TV.
Probably more than what you wanted to know but firmware installs and upgrades on jailbroken devices is somewhat complicated.

I have another appletv that was jailbroken prior to the latest updates. Is there anyway I can clone it to the appletv that is now running 5.1?
