I didn't research it much, but I was a little confuzzled by a webpage that led me to think I could (A person needs 10 posts to insert a link?). I was able to put Cyan on my VZW Droid X, e.g.
Was that supposed to be helpful?
A little history...
The Verizon XT1060 has always shipped with a locked bootloader. This prevents flashing ROMs or Parts (like custom recovery) from being flashed to the phone. Only Roms signed by Moto and intended for that model and carrier can be flashed.
A Developer Edition For Verizon Moto X was available from Moto's web site only. For that device, Moto would give out the bootloader unlock code. Once unlocked, you could flash 3rd party roms and parts. With the Dev Edition, you did not void your warranty while doing this.
Verizon stores and Moto's Moto Maker web site also sold the X for Verizon, but for these not Developer Editions, you could NOT get the BootLoader Unlock code.
Later, someone was able to gain access to a database of IMEI numbers and their BootLoader Unlock codes, even for Verizon Non-Dev Editions and started selling them via a China web site, and later Middle Man. While it went away for a little over a month, it later came back. It has recently shut down again.
JCASE and others had found a vulnerability they could exploit to unlock the bootloader, no unlock code needed. Its called Sunshine. But it only works on phones which haven't even been upgraded to 4.4.4.
So depending on what you read, it could be "dated" and written at a time where you could have purchased the bootloader unlock code from the China Website or Middleman.
