There was once a minor league baseball team in Canada called the Ottawa Lynx. The professional basketball team for London in the UK SuperLeague is known as the London Leopards. And there’s a Super 14 Rugby club known as the Central (South Africa) Cheetahs.
For obvious reasons I don’t think “Cheetahs” would be a popular sports name in the US, especially in Boston!
I give you the Minnesota Lynx of the WNBA, the Lafayette College Leopards, and the St. Joseph’s College Pumas. There’s also the Puma shoe company. If Wikipedia is correct, cougars, catamounts, and pumas are all the same animal. The category would also include Penn State’s nittany (mountain) lion. I don’t see any cheetahs and I think Duke explained why.
