Yeah, possible, but there's a great deal of skepticism among many of
the planet finding crowd.
Reactions not normally found on the nitroxy Earth may be a non-living
source of the chemicals in the signature of a planet that probably
isn't nitroxy, among other objections that need to be addressed.
Articles on Ars Technica and elsewhere have more on the objections.
