Is an AR-10mm kit the same as an AR-10 kit?

No. An AR-10mm kit is a pistol-caliber AR configuration chambered in 10mm Auto, while an AR-10 generally refers to the larger-frame rifle platform used for cartridges such as .308 Winchester and 6.5 Creedmoor. Despite the similar names, they are different platforms and should not be treated as interchangeable.
