Units are defined on the first page of the core rules.
When you add models to your roster, they are added in "units" of one or more models, as defined by their datasheet.
So yes, a transport is a unit, and it can hold objectives. All armies have some kind of special rule for certain units (usually Troops units) to be better at capturing objectives, though.
