Generally, one of the reasons people use PDF is because it doesn't repaginate. So complex, graphic-heavy layouts stay how they were designed.
So if the PDF file doesn't offer the same "aA" icon that an ePub file does, I don't think you can upsize the text. (I don't have any PDF files in iBooks at present to really test this, but Apple's KB here says users cannot change font size with PDF: http://support.apple.com/kb/HT4168 ).
Look for a text or ePub version of the PDF, or Tip #5 here suggests you might be able to convert it yourself:
otherwise how can you read a full pdf page in the iphone screen?
some people are more willing to strain their eyes than others. I've managed it.
