Outdside of the fact that the Bigleaf is one species and the little leaves are another, I don't think that long internodes automatically mean
never reducible. But, the
amount of reduction varies widely from species to species and some do not reduce to bonsai standards. Depending upon your standards. The small leaves you show are immature and will likely grow to the same relative length of the ordinary un-reduced leaf to un-reduced petiole relationship. I'd like to see them in September. And I'd like to see you reduce the Bigleaf to whatever that would be. I've said before, many times, that Norway does not reduce much more than 50%, which is still not bonsai.
