What you need to be careful of for Lab machines is if you have an Enterprise agreement licensing PC's for Windows per Device,
then adding the SCCM client would generally make those devices managed and need to be included in the qualified device count.
Industry devices would still remain exempt so can have SCCM CAL on them.
