Yes, if you mean "used as a trademark" or "registered as a trademark", but only if it is used in association with the commercial sale of some goods or services.
For example, the word "Seabiscuit" and the image of a horse's head was used as a trademark in 1944 and registered in 1945 association with fresh citrus fruits. US Reg: 0413733, on Ser no. 71478196.

They don't really have a name for a group of race horses as far as I know. Cause generally when racing, they compete against each other. And it's a solo race for the win. So there is no association with the other horses, like for example a team of basketball players. There is no real name for a pack of race horses or a herde of race horses, or horde of race horses..............
