A bird may have deposited some seeds nearby if it visited to feed on the Trumpet Honeysuckle berries at some point. It is an ironic (or frustrating) occurrence that the weedy Honeysuckle is growing up through the native. Since, as you have noticed, leaf shape can vary some with stem age, growth stage (flowering or not), and even light exposure, it may be simplest to trace the invasive Honeysuckle stem(s) back to their origin and trim them there. This is perhaps tedious but the only way to be sure of what you're removing. When older, bark differences between the two may be more distinctive, but at this point, they're likely too young for this and it is certainly not desirable to wait that long before removing the interloper.
