Great thanks to @aeg!
For some reasons straight googling didn't point me to this document.
Yep. I love Moto! Take the same die, put in the larger package, hide an information about it in some addenums to documentation...
What may go wrong?

The only difference between CQPF-208 and CQPF-240 is 8 spare pins per side - 4 at the left and 4 at the right of each sides of four.
And Moto takes is literally!
Comparing pinouts pointed out by @aeg and "the official one" CQFP-208 for FE package shows that 4 left/right outer pins of
each side of CQPF-240 package are just unconnected. With one exception around 96-96 and 117 pins.
Well. I'll go and correct my symbols in KiCAD.
