Well game-wise yes, but lore-wise no. Since it is the year 3050 currently, these Omnimechs are new machines at the time, so the IS really did not know what to call them. So they made up these nicknames either out of reputation like the Dire Wolf's nickname of "Daishi" (Japanese for "Great Death") or their appearance like the Mad Dog's nickname of "Vulture" or "Hagetaka" (Japanese version of the former) due to its bird-like stature.
Speaking of game-wise, I find it amusing on the Clan Packages that the Omnimech Bundles use IS designations, but shows the Clan real names when you view the details.
