Since the replacement of the mother board (within warranty term), the serial number and machine type model number are shown “invalid” in BIOS or windows program like Lenovo Companion.
Lenovo provide flashing BIOS utility from within Windows, and that tool don’t provide option to flash the serial number and machine type model number.
The search within Lenovo support community didn’t provide any answer for this need.
Is there any solution?

Lenovo authorized service technicians have a utility that they use to writed those changes to the BIOS, and they should have taken care of that for you when they replaced the motherboard, so it appears that they screwed up.
I am pretty sure that they will not send you that tool, so you will have to take the system to a local Lenovo service center, if there is one nearby, to have that corrected. If not, I would contact warranty support and see what they can do to assist you.
