Yes, but we are talking about taps that are hundreds of feet away in line length. To "push" beer through that much line would take an IMMENSE amount of gas pressure to combat line resistance and keep the system in balance.
A LOT of long draw systems, especially THIS long, rely on inline pumps to keep line pressure up and only use enough CO2 to feed the pumps. Then they boost the CO2 volumes at the dispensery through inline methods.
A paper article I was shown, Sports Illustrated IIRC, indicated that they relied solely on gas pressure for service and carbonation maintenance.
