Not really. Edit: well I am no academically qualified to truly question Czerny, but you could maybe play these dynamics very subtly and it would sound fine.
You can do whatever makes you happy. Seriously. But know that it wasn't the composer's intent, nor at all the style of the time.
Dynamics in Baroque literature definitely have a place. Subtle shading and highlighting of certain melodies and phrases can give the music further dimension. But bluntly wielding FFs and PPs to maudlin excess can ruin the integrity of the music.
