It's kinda hard because the CPU that makes MacBooks so power-efficient is Apple's own design, not from an external vendor. So Lenovo can't use it, nor can anyone else; they'd have to design their own, or partner with Qualcomm maybe. And we just don't see anyone working on ARM-based laptop CPUs right now unfortunately. It would be nice though.
