It is interesting because while researching, I found a woodworking site that claims this is simply not true. The purpose of mixing the mineral spirits with a raw oil is to help it dry more quickly. The absorption has more to do with the type of wood.
Subjectively, it does seem that thinned oil will penetrate further than neat.
I have used a lot of tung oil (which has similar properties to linseed oil) for treating and finishing wood and I generally find that using it neat results in very limited penetration - it builds a nice, protective layer on the surface but rarely reaches more than 2 or 3 millimeters into the timber.
Mixing the oil with white spirit (the cheapest solvent available around here - turps and citrus thinners aren't easy to procure) I find it roughly doubles the penetration depth. Of course, I have to apply more coats (gradually reducing the amount of solvent) to get the same surface finish.
I'm judging the penetration by observing the colour/texture change as I cross-cut timber, by the way. I often sand + treat an entire plank or pole before cutting it to dimension, then re-treat the end grain.

We have started using wood charring aka shou sugi ban for our wood preservation needs. Here are some helpful threads:
