From a purely physical point of view, a computer monitor can only produce a spectrum of light (photon histogram) that has spikes on the wavelengths for red, green and blue. These spectra reproduce the vast majority of colors that are perceptible to humans with normal vision. However, the "colored discs" in the article exploit the fact that two colors that are perceived as identical, can in fact be produced by (at least) two different spectra of light. Tetracromats can differentiate between some of these spectra, whereas people with normal vision can not. (A simple example: The color cyan can be produced by additively combining the spectra of blue and green, but can also be produced by creating photons with only the wavelength of cyan, 490-520nm according to Wikipedia. A person with normal color vision would not be able to differentiate between these two light sources, whereas a measurement device or perhaps a tetrachromat could. A computer monitor can only produce the first of these). So the answer to your question is no, unfortunately.
