Erm... Considering that's also got the negative "bottom out" spring I would say that yes, you could run it but it's gonna be hella' soft and bottom out easily
the bottom one has a small amount of what's left of the topout spring, the top one is the one I will be running in the fork, basically, the top one is normal apart from a 30mm spacer and the bottom one should look the same as the top one, except without the black bar inside it
Yeah, as it compresses the spring, meaning the first 30mm (that you would have got before you lowered it) will no longer be there and the 70mm of stiffer travel will be left
