Theoretically, yes, but most of the reinforcement points where you are to place the jack at are right near the wheels, not in the center of the car. But a guy on the Equinox/Terrain forum has a pinch weld jack adapter for his floor jack that he uses to lift up both wheels.

Looks like there are several places that sell a version listed in the thread.
FWIW, the scissor jack from my Mustang when extended all the way would raise both tires off the ground. As long as I broke all the lug nuts loose prior to jacking it up, I could rotate the tires that way. A bit shaky, but it worked.
