I have a main document (manuscript) and a supplemental document.
I wonder if there is a way that I can "link" the two (make them recognize each other) so that section, equation, and figure references across documents are recognized?

You can use the xr package with the following setup in the header of both files
\usepackage{xr-hyper}
\usepackage{hyperref}
\externaldocument[]{name_of_other_file_without_extension}
You can then just use regular \ref{fig:label name} like you would in the same document.
Placing this header info at the bottom on the header will likely reduce package conflicts regarding hyperref.
