Yes you could be disfellowshipped for loose conduct and uncleanness, it's in the elders' book. I don't think the phrase "brazen conduct" is a terribly meaningful change in itself.
I don't think you could be DFd for uncleanness prior to the re-written book in 2010. It was counsel only. Loose Conduct required multiple counseling (and suggested even a marking talk) before DFing could apply. Which meant that once counseled, the "guilty party" had to commit get caught at the same "sin" again before DFing action could be taken.
If you see different in the OLD Sheparding Book, cite the page number, please.
