In brief: Dead space in lung

Dead space is a term used to describe an area of the lung where gas exchange cannot occur - it does not mean dead lung tissue.
Everyone has dead space and it is comprised mainly of your airways. It is measured as a percentage. Dead space is affected by many variables including the size of the breath we inhale. Dead space typically decreases as we exercise because we take bigger breaths.

In brief: Yes

Particularly emphysema, bronchiectass, bullous disease will lead to ineffective air save= dead save.
This is not dead lung which can happen with infection and pulmonary emboli.
