Would Apple still exist without Wozniak? Nobody knows, which is why such arguments are always about sour grapes and nothing more.
I do have high expectations from engineers who should be knowledgeable enough to know that revolutions and hurricanes happen not because of a single reason, but because of a sequence of events and fortunes that happen at the same time, and if you analyze this, trying to get to the root of what led to the rise of an industry, you'll end-up like Mandelbrot, discovering fractals, which is otherwise in the curriculum of universities these days.

Luckily we can test your theory. Woz left Apple in the late 1980s. What happened to Apple. Did it die? No. From the history of Apple, its obvious that Jobs with Woz is able to make a massive influence on Apple.
The question is less "Can a company like Apple function without a Woz" and more "Can a company like Apple form without a Woz".
To 'test' this theory it would be better to find an Apple-like company that formed without an obviously Woz-like figure. I think there are several examples of varying quality.
