Can a Canon 7d internal flash trigger a Speedlite EZ flash?
I know that the new 7D has the capability to be the master flash to trigger EX slave flashes, but can it trigger an older EZ flash?
It shouldn't matter what slave flash you use, though you may want to contact Canon and ask them or read the owner's manual. It should have something in there.

I've only had my 7D for a few weeks and had no reason to try it because I only have 580EX and 580EXII speedlites. The only mention of the EZ series states; "With an EZ/E/EG/ML/TL-series Speedlite set in TTL or A-TTL autoflash mode, the flash can be fired at full output only." But this appears to reference a flash that is hotshoe mounted rather than one fired as a wireless slave.
You might want to check for answers in the forums at DPReview.com or another dedicated photoforum such as FredMiranda.com. You'll find far more actual 7D owners at those sites than on Yahoo Answers. One option would be to take your EZ flash with your to the store and ask if you can try to fire it wirelessly with the 7D. Doing so won't endanger the camera or flash so they shouldn't have a problem with it. I can tell you from experience that your lens and hood can prevent your slave flash from "seeing" the pop-up flash.
