The way I see it, a Kekkai Genkai is a genetic trait, and someone can only possess a Kekkai Genkai ability if they do so through genetic means. If the ability is found in a person's genes, and they are shown using it they have a Kekkai Genkai. If a person uses the genetic material of someone else to attain an ability it is still a Kekkai Genkai by virtue of relying on said DNA. Cases such as Naruto using Lava Release have not been classified as Kekkai Genkai as they do not make use of genetic material or DNA, instead they are the result of living chakra. Unless Kishi calls the use of a tailed beasts power Kekkai Genkai, it would be misleading for us to do so.
