And if not, why not?

The strings don't buzz when they're fretted at the first fret because there is clearance of at least a few 1/10ths of a mm to the next fret. The strings are obviously not co planar with the frets as the action above the frets increases as you move down the fingerboard towards the saddle. If there was no action above the next fret the string would be damped because the string still has a small amount of amplitude even right next to its nodal points. Anywhere you fret on a fingerboard the string will have a small amount of clearance above the fret in front of it or it would buzz.
The strings don't buzz when you CAPO them because they are being fretted at that particular fret. That's different than the strings being able to clear the fret in front of them. There will still be clearance to the frets in front of the frets that are being capo'd.
