It’s certainly possible. the fact that no makuta were left alive is something we see from Teridax’s point of view after he killed all the ones on Destral. It makes sense that he would have kept a list of those that were around.
But during the Destiny War, the order was going around killing Makuta, so not all would be accounted for. And there are likely limits to Teridax’s omniscience, seeing as he had to teleport the shadow Takanuvas to kill alternate Teridax (rather than simply ending him by godly power)
so why not have one or more Makuta hiding among the Destiny war dead?
