It's a Rom D7, aka "K-R". The ship itself is canon, the label is just there to distinguish it from the Kli D7. I doubt it will qualify for T-5ness, but it'll briefly be a battlecruiser the Rommies can use with Klingon-level agility, something other canonical Rom cruisers would probably lack: You never see a D'Deridex move, and it gets outmaneuvered by even Galaxies.

KR does not stand for anything related to "Romulan".
It stands for "Kestrel" and actually applies to the transferred D6, while the D7s were called K7R.
In FASA's material they were called V-11 "Stormbird".
In recent novels Romulan versions of the D7 are called "Ventarix", but what they're called in canon is unknown.
*EDIT: I see your edited your post while I wrote my response*
KR is a designation from the old Star Fleet Battles game. It doesn't represent any name (not even Kestrel, though that may have become the accepted interpretation).
The game suggested the Romulans recieved several classes of ships from the Klingons in exchange for the Cloak. The KR was based on the D6 cruiser. The K5R was another example of this naming convention. Basically, it amounted to K-lingon R-efit or K-lingon R-omluan refit. I don't recall it ever being officially designated one way or another, it was largely left to individual interpretation.
Once, I was simply called Mojo. Now, I'm forced into a new name, but don't be fooled, I'm the original STO Mojo!
