No "as if" needed: the fan is oscillating back and forth according to
a program. The fan is a very simple computer. Livers and kidneys are
more complex computers. The brain is a much more complex computer.
I am using "computer" in the general sense of physical systems that
evolve in time and interact with their environment according to
physical laws and stored programs. In this sense, yes, considering
everything as a computer is a useful framework.
