Most of the arguments in the article are agnostic to the size metric - offhand, I cannot think of any claim that is invalidated by changing to your measure. Furthermore, it is the proponents of short functions quoted in the article who are using line count as a metric, so it is not as if the author of this article has created a straw man by choosing a misleading metric.
