Liszt has multiple études with the tempo marking Molto Vivace, while the Transcendental one is the most well known, the current title does nothing to differentiate it from, for example, the Douze Grandes Études version which is also Molto Vivace.

Indeed. The same goes for pretty much all of the popular nicknames for Chopin's pieces, such as 'Minute Waltz' or 'Raindrop Prelude', which were either added by the publisher or popularized by a prominent musician (Von Bülow in the case of the Chopin preludes).
