Grubby has never checked kernel/initram options as there is really no way for grubby to know what options exist at all levels, especially since one can add options that get used during startup.
Move the --no-etc-grub-update option to the end, something about that option is eating the "--args=" part and then grubby believes that iomem=relaxed is a grubby option. I don't see where the --no-etc-grub-update takes an option so it must be something screwed up in grubby in regards to that option. I tested and duplicated your error and tested the fix on f42.
