From Microsoft - no. Adobe has Acrobat which does this, but there is no Visual Studio integration. I don't know of any product that creates PDF files that integrates with Visual Studio.

Go to Adobe's site for the specification on the PDF file format. It'll probably be behind the Developer site, which, last I checked, was a pay-to-play subscription.

Since there is no support for PDF files in the .NET Framework, you'll have to use some third party library that does this, like PDFNet. You'll have to check with the documenation on the library you're using on exactly how to do this.

Then you'll definately need to subscribe to Adobes Developer site to get the support to build this library. After that, you'll have to come up with your own code snippets to demonstrate using your own library to add a checkbox.
