Sorry, this isn't possible.  The 16-bit Linux boot protocol assumes that
BIOS interfaces are available, which isn't the case with EFI; and in any
case I don't believe that an EFI-based boot loader can guarantee to be
able to set up the particular memory ranges required by the 16-bit boot
protocol.

If memtest86+ can work without BIOS calls, then somebody needs to modify
it to be usable via the 32-bit boot protocol.
