I guess technically true, but the cell channels are vastly more complex and much harder to measure. Chemical gradients can pass electric currents, but they can also trigger other chemical cascades and cause physical changes in the cell that may not be reflected when a charge is applied. Logic is also fairly consistent across computer systems, where biological systems can function differently from person to person, and even within the same person at different points in time. There are so many more variables with the living system.
