In theory, yes. Pretty much any microcontroller board with a few GPIOs can be used as programmer given that someone writes some firmware which allows doing that and a flashrom "driver" which works together with that firmware.
For the lauchpad there's no such project I know of (yet), though I've been thinking about doing this myself at some point. It's not very high on my TODO list though, there are many others things I want to finish.
