That depends on boot loader, not Linux I think.
Linux has support for 4k sector drive, but if the boot loader
doesn't, it can't fetch the kernel into memory and load Linux.

Legacy grub makes use of BIOS interrupt service and thus shouldn't
be able to support 4k sector drive, I don't know the status of grub2.
