There is a common, generic alternative word for champagne: "Sparkling wine", so your example is really far-fetched.

Meanwhile, several alternatives have had success with their own name, such as Cava.

Sparkling wine might not have been made with the champagne method, and some people think that's important.

Cava uses the champagne method; prosecco uses Metodo Martinotti. Some wines just use injected carbon dioxide.
