Vinyl siding can be installed directly over wall sheathing wood siding or stucco. Its primary purpose is to prevent air and water leaks that may have seeped past the vinyl exterior. Tar paper does not offer this. I have seen literally hundreds of houses stripped of asbestos siding that had 15 felt under it.

These channels help direct water quickly down and away from the exterior siding material. Building paper also called house wrap is a strong fibrous paper that blocks water and moisture from entering from the outside but allows moist air to pass through from the inside preventing a buildup of moisture inside walls that can lead to mold. This is a good thing.

In fact many builders disagree on the effectiveness of house wraps altogether and while some builders will only install 15 pound asphalt saturated felt paper underneath exterior siding others swear by plastic fabric house wraps such as typar or tyvek. To sum it up house wrap is a lightweight paper like material that is most often used to completely cover the house directly on top of the sheathing and behind the vinyl siding.
