Linear regression isn't exclusive to statistics. One can, for example, find a chapter on linear regression in most machine learning textbooks, without reference to statistics. I've been on both sides of the fence, but it's always the statisticians who take the perspective of, "yeah, well you didn't study model diagnostics, ANOVA, QQ plots, ... so you don't know linear regression". Linear regression as described in this post (which is pretty much what you find in Andrew Ng's famed machine learning course) can be used as an introductory stepping stone to logistic regression, neural networks, etc.
