They might put a C-series modem in the laptop, but from a manufacturing perspective it makes no sense to combine it with the CPU. It would add significant cost, which can only be justified by the speed and power consumption of ultra-high-speed interfaces (why they put the memory in the same package as the CPU die(s) for the M-series processors).

There's nowhere enough speed involved to make it worthwhile for a wireless modem that might sometimes hit single-digit gigabits-per-second versus memory which is triple-digit gigabytes-per-second. It's like four orders-of-magnitude difference.
