No; it is not, as yet.

The pdf-driver for Xy-graphics primitives has not been implemented
in PDF, so your options are:

  1.  use  dvips+ghostscript for the whole document;
  2.  handle the diagrams as separate images,
      (using dvips+ghostscript -E then import them
       into your pdfLaTeX document);
  3.  use colours, rather than line-thickness to convey
      the meaning that you are trying to express;

Or, the most desirable...

  4.  contribute to the development of a full graphics
      back-end into PDF, analogous to xyps .

That is correct.
