Well the TeXworks previewer can certainly read PDF-1.5 files made using 
the settings being discussed here. TeXworks uses the Poppler library, 
and that is free, and I'm sure is used by other viewers. So you can 
certainly read a PDF-1.5 file (i.e. one that says "PDF-1.5" in the 
Document Properties with Reader) using free software.
