If you're talking violin/cello-type volume swells, yeah, it'll do that.
If you mean that it will control a setting on the fuzz pedal, nope.
However, if you put the volume pedal before the fuzz, you can control the breakup and volume of the fuzz which interacts somewhat with the tone. Many guitarists do this with either a volume pedal, or by using the volume knob on their guitars.
However, you can turn a volume pedal into an expression pedal by using insert cables (cable that has two mono ends and one stereo end) and figuring out which way the plugs are supposed to go. However, this isn't usually ideal because the pedal sweep, potentiometer taper, and/or resistance of the potentiometer in the recomended expression pedal may differ from that of the volume pedal that you own.
