Do you think an image taken at 100mm and another taken at 400mm, from the same position, are comparable images?

Comparable with respect to perspective and "compression" - absolutely. With respect to that attribute, they are close to identical in the parts that are common to both images. Resolution and DoF will differ of course.

Given, of course, that you are shooting in the exact same direction.

But they're not comparable images.  Unless you think a landscape can be compared with a portrait.

When we take a picture, we have a certain goal, a certain framing in mind.  Using a longer focal length will force you into a position to get more compression in that frame.
