A 1 line change can be just as dangerous as 400 line one. I'd argue that alot of the so called "small" changes are just as tricky to review as a big one simply because the context of what is being changed isn't really a part of the PR. (i.e the reviewer has to trace through the framing code to really understand what's going on.) The difficult part is keeping enough context floating to know when a deeper dive is required.
