I tried what you proposed. The entry was added as Boot000.
However, booting from the KDE Live stick was still not possible.
After rebooting via grub2 the new entry was gone, as follows.
# efibootmgr -v
BootNext: 0005
BootCurrent: 0007
Timeout: 0 seconds
BootOrder: 0005,0007,0008
Boot0005* Sony Original
HD(1,800,82000,b1eeeec6-0c0e-4230-a7e4-762fbc0cc576)File(\EFI\Microsoft\Boot\bootmgfw.efi)
Boot0007* Windows Boot Manager
HD(3,363800,82000,674c63b1-dc34-4b86-a233-b397a638f5e0)File(\EFI\Microsoft\Boot\bootmgfw.efi)
Boot0008* Windows Boot Manager
HD(5,425800,e9b1000,7b64ff3b-e062-4b75-aec7-b5f8fa073e88)File(\EFI\Boot\bootx64.efi)
I have even deleted all entries except Boot0005 with the effect that the
entries Boot0007 and Boot0008 are restored. Boot0008 is probably the result of
an interim attempt to solve the boot problem by defining a separate EFI
partition for openSUSE. But this did not work and I deleted this partition
again for the nth installation of openSUSE on my computer.
# lsblk --fs
NAME FSTYPE LABEL UUID
MOUNTPOINT
sda
├─sda1 vfat SONYSYS F8E1-6DFA
/sda/sda1
├─sda2 ntfs Windows RE tools FCF6E1DEF6E198E2
├─sda3 vfat A7F2-5FA8
/boot/efi
├─sda4
├─sda5 ntfs E8BEF800BEF7C55A

[SWAP]
The following steps seem to be made on my Sony Vaio SV132A1CM:
1. The program \EFI\Microsoft\Boot\bootmgfw.efi on the SONYSYS partition is
started first.
2. It transfers the control to \EFI\Microsoft\Boot\bootmgfw.efi on the EFI
partition.
The BIOS expects the program bootmgfw.efi to Boot Windows there.
The only way to take control of the boot process was in my experience to
replace bootmgfw.efi with grubx64.efi and rename it to bootmgfw.efi. This fools
the program in SONYSYS.
The further procedure is explained in
https://bugzilla.novell.com/show_bug.cgi?id=846752#c4
I know that this procedure cannot be used by you.
But neverlheless it would be nice to be able to start an installed system from
an installation of live system on a USB stick.
The procedure to find an installed openSUSE would have to look for
/boot/efi/opensuse/grubx64.efi
or look for a partition with a /boot/grub2 directory and take the required
information from there to start the installed system.
