It might be considered trademark infringement, so your mother's correct.
I doubt that PepsiCo would come after you for naming your horse Pepsicola, though.
There was a big Arabian breeder back in the 1980s who named one of their stallions Baskin Robbins. I don't think BR ever sued them. It was free publicity, after all.
