    Maybe. You must be able to maintain enough downward slope in the extension so that the water will drain properly. This isn't much for a 4' run (about 1/8" drop), so that may not be an issue.

    Another problem is venting. Normally, a sink is drain would be vented up the wall and connected in the vent stack in the attic. Since there is no wall going up to the ceiling for an island, it has to be done a bit differently. The best venting solution for an island is called a "Chicago loop". A picture is worth 1000 words, so have a look at the picture on the wikipedia page http://en.wikipedia.org/wiki/Chicago_Loop_(plumbing)

    Getting the proper venting may be more of a problem with your extension than the actual waste line.

    Another option would be to use an air admittance valve to handle the venting, but results certainly vary with this option. Some have good luck with them, I have replaced a few so I try to avoid them at all costs. Use your judgement.
