I know this is not a common scenario, but for the few people that upgraded a Mac originally equipped with a Core Duo processor to a Core 2 Duo processor, here is the procedure. I have an iMac version 4,1 that I upgraded years ago, and it worked. The person who found the solution had an upgraded Mac Mini. You will need a second computer that is Lion capable for this tip to work.
As always, Make sure you have a backup of the original install! This worked for me, but always be prepared for the worst.
I made, and used, a Lion Mac OS X Install ESD on a thumb drive. Instructions to make one can be found all over the Mac centric web sites. Then follow this procedure:

Who thread ran this WiFI card on mac os sierra 10.12.6? Install version. For my model, I must presse F2 at boot. Press F9 to reset default settings. Enable 'F12 Boot Menu' in Main tab. Set Supervisor Password in Security tab. Disable 'Secure Boot' in Boot tab. On another Mac computer, follow steps 1 and 2 of UniBeast: Install macOS Sierra Guide to create a bootable USB.

  • Put the unsupported Mac in Target Disk mode and plug it into a Lion supported Mac.
  • Run the Lion installer and make sure to choose your unsupported Mac's hard drive. Let the install finish.
  • Boot back into the supported Mac's OS, and put the unsupported Mac back to target disk mode.
  • Delete the PlatformSupport.plist at /System/Library/CoreServices on the unsupported Mac's hard drive.
  • Reboot the Unsupported Mac and it should boot into Lion normally.

[crarko adds: I don't have the equipment to try this, but it seems plausible. As recommended in the hint, have a complete system backup handy in case something goes awry.]

Question :

I read somewhere that it is possible to install the latest version of OSX 10.10 Yosemite on my Mac, even though the official installer refuses to install.

Can you give me any directions ?

Install Catalina On Old Mac

Installing newer versions of OSX on slightly older Macs that do not meet the official system requirements can be done using MacPostFactor (MCPF).

MacPostFactor (MCPF) also supports installing OSX versions up to OSX 10.10 Yosemite on older Macs. And a new version that supports installing OSX 10.11 El_Capitan is in the works.
