I think TL-10A is just C-701/702 renamed or by a competiting factory trying to offer a similar product to the same market niche. There is a very thin line between TV guided antiship missiles and TV guided air to surface missiles, and I am guessing this is probably more of the latter.
Just a visual comparison, but I'm pretty sure that it isn't a version of the C-702. It's generally slimmer and probably lighter (which throws off the sinodefence page's estimated weight for the YJ-7).
Also, any info on the TL-6B? It looks fatter and has four different wings.
Re designations:
"TL" as in TL-10 means ???? -and is a manufacturer's label(?)
"JJ" is used for air-launched versions in Chinese service(?)
So a JJ-10 = TL-10 = YJ-10??? .... = C-100? / C-1000???
