Seems unlikely. The Andorrans have chosen to stay independent this long; why would Catalan independence change that?
It's in the link I shared.
The historic and official language is Catalan, a Romance language. The Andorran government encourages the use of Catalan. It funds a Commission for Catalan Toponymy in Andorra and provides free Catalan classes to assist immigrants.

Catalan 38.8%

I know they speak Catalan in Andorra. But they also speak Spanish and have never expressed the slightest desire to join Spain. Moreover, nationality is about more than language, else why wouldn't Austria merge with Germany? Or Luxembourg with France? Or, maybe most to the point, San Marino with Italy?
Luxembourg main language isn't French, but Luxembourgish.
