I would be curious to know what errors you encountered. Did the CD simply refuse to boot? Anything mentioned about the chipset? Reading up on Google, it looks like Linux is using something called UEFI but Apple only supports EFI booting. I read this from one article:
Caution for Mac owners
From Ubuntu 11.04 onwards (x86_64 only), the ISO CD supports UEFI booting and the Ubuntu installer will try to set up the bootloader for (U)EFI boot. But the installer formats the EFI System Partition to FAT16 (even if the filesystem is non-empty) and also uses efibootmgr, therefore Intel Macs may fail to boot due to corrupted firmware. This feature is not recommended on Mac models because it can corrupt the firmware. You will need to reflash the firmware to repair it.
Here is the link to the full article: https://help.ubuntu.com/community/UEFIBooting
I don't think this is Apple intentionally locking anyone out. It is that Apple's firmware does not (yet) support UEFI.
