..... no. If you put a capo on a fret, you're essentially putting a temporary bar on that fret.
For example... if you capo the first fret on a tenor, GCEA becomes ADF#B. Tenors usually are bigger and have longer necks than a concert or soprano. As a result, tenors usually have more frets than concerts, and concerts have more frets than sopranos. The number of frets determines how many notes you can hit. The more frets, the more notes.
But if you capo a fret, the frets above the capo become useless... so if you capo a tenor, you'll have less frets to play with.
