To use a pantone colour you define a separation color space, put it in the ColorSpace resources dictionary from the page, and refer to it through the CS/cs operators. You select the tint with other operators.
The separation color space must define a tint transform to RGB or CMYK, in the form of a function, which is used for screen display. There is no built in knowledge of pantone names in Acrobat.
This is not a simple subtitition. But the full details are in the PDF Reference. In case you were thinking PDF files can be simply edited in a text editor: they CANNOT, the xref tables must be rebuilt.
