Sure, but that uses audible tones; the method described in the article employs ultrasonic tones, and I think (parent (parent)) is questioning the likelihood that cheap(ish) laptop audio hardware can be reliably depended upon to generate and detect such high frequencies.

There already exists browser based implementations of basic ultrasonic networking on github - https://github.com/borismus/sonicnet.js/tree/master/lib

Assuming decent error checking, the question isn't whether you could do it, it is just how fast would it be.
