If you can print, it means it’s possible. Maybe the built-in print to pdf driver transfers the DRM, but I’m convinced there is one that wouldn’t.
Edit: Or another idea, you can use features in screenshot programs like XShare that scroll through the document and take multiple screenshots and assemble it as a single image, or even PDF iirc, and that one wouldn’t have DRM (but wouldn’t be searchable without OCR.)
