Not easily. SNES sound isn't stored as samples you can simply extract. Rather, it is generated on the fly by programs written for the SPC700 processor. If you want to capture a specific sound, the best bet is to record the output of an emulator while you're playing the game and edit the output down to what you want.
I'll go one better for ya - use Audio Hijack while playing the SNES sounds from RB's Audio Overload app. No need to play with game controls and dealing with other sfx in the mix - just play the .smc files (the ones from the site listed above are the best) and then do as Richard suggests and cut down the sound to what you want for output in any sound editing app.
The other option, if you have CrossOver, is to install Winamp 5 or later and download and install the NotSoFatso and SNESAmp plugins for it (Highly Experimental works wonders for Playstation/PS2 audio files). You can then choose the output to be to disk and it'll play the song for however long the tag says to in the SNES music file. That'll save the song directly to disk for the preset amount of time, usually in seconds, and no editing is needed. That's how I got WAV files of those songs onto my ipod.
