Hi,
So far as i know, you can use a reader control to read PDF file's data, them set the data as the datasource to the RDLC report control. If you only want to embedded pdf file in RDLC, I suggest you display it in the page.
There is a document about how to Embed PDFs into a Web Page with a Custom Control, for more information, please refer to the link below:

Hope it's useful for you.
Best Regards,
