Can you attach the image of this logo generated by Intel Processor? On what base you have concluded that this logo is generated in CPU? Can you explain why you think that Intel forum for Intel NUC computers is the right forum for asking how to change logo in Panasonic computer?
There are no logos in the processor. All logos are generated by the BIOS. Whomever told you otherwise is an incompetent that you shouldn't be listening to.
