You cant answer the question by brewing in one. It will hold liquid, the yeast will ferment and you will end up with beer. The issue is the leaching of potentially toxic/carcinogenic by-products in your beer. All plastic water bottles leach to some degree into the water, even PET-1. You also should note the bottle you are planning on using is made for water and hasn't been tested with beer which is acidic and contains a solvent (EtOH). In addition most PET bottles are intended to be safe for single use. With age they undergo thermal and oxidative degradation.
Having said that, it is probably safe to use as long as it is PET 1 and probably wont impart a detectable off flavor. On the other hand glass definitely is and wont.
