It may be that the Lenovo BIOS/firmware searches for that specific
Microsoft location

  EFI/Microsoft/Boot/bootmgfw.efi

Onto which i radically (according to docu) moved refind_x64.efi:

  #?0|kent:~# ll /mnt/EFI/Microsoft/Boot/bootmg*
  -rwxr-xr-x 1 root root 1453056 Sep 14  2018 /mnt/EFI/Microsoft/Boot/bootmgr.efi
  -rwxr-xr-x 1 root root 1469752 Mar 21 17:43 /mnt/EFI/Microsoft/Boot/bootmgfw.efi.safe
  -rwxr-xr-x 1 root root  208776 Mar 21 17:43 /mnt/EFI/Microsoft/Boot/bootmgfw.efi

and that now finds its normal installation (etc.), simply copied
via cp(1):

  #?0|kent:~# ll /mnt/EFI/refind/
  total 260
  drwxr-xr-x 2 root root   4096 Mar 21 17:13 drivers_x64
  -rwxr-xr-x 1 root root 208776 Mar 21 17:14 refind_x64.efi
