On Ubuntu 16.04, uefi secure boot enabled, grub-efi package 2.02~beta2-36ubuntu3.15, the original problem has been fixed, like the suggestion in the original posting (just use shim) , but now the --no- uefi-secure-boot switch on grub-install does not cause grubx64.efi to be used as .../EFI/Boot/bootx64.efi, instead the legacy core.img is used. There is apparently no way to install grub to a removable disk for use on a non-secure boot UEFI system from a 16.04 secure boot system.
