I'd say it's a solid "no", and the author says as much in the paper.

> We transmitted the data with a bit rate of 1 bit/sec, which is shown to be the minimal time to generate a signal which is strong enough for modulation. The BER for PC-1 is presented in Table VI. As can be seen, the BER of 1% - 5% is maintained between 0 - 90 cm. With a greater distance of 120 cm, the BER is significantly higher and reaches 15%. With PC-2 and PC-3, the bit error rates (BER) are less than 5% only in short proximity up to 30 cm, and hence the attack is relevant only for short ranges in these computers.

This particular attack is a weak 6 GHz signal that can exfil about 1 bit/s from a metre away. It's neat, but impractical.
