Is it possible to link mission luas together in BF1 so that if you win the first battle, you automatically go to the second, and if you are defeated, you don't?

I think what your asking is, is it possible to create a campeign group of missions, and I think it's been done before, but I'm not sure how, I suggest you ask Maveritchell or another experienced map modder.

no, what you are talking about is a mappack or just a set of several addon maps released at once to the SWBF players

what I'm asking about is using any kind of lua command to literally run one mission after another

I know, and again, I've seen it done before, you mean like having one map start, and when it's done, go to the next one, like having a group of maps under only one map name, (like the original campeign for the game)

That wouldnt be possible unless you edited missionlist.lua in shell.lvl and had the shell scripts to add a new campaign. other wise you cant do that. the only thing close ti simulating that would be too make gcw and cw load dif maps.
