I haven't tested that specifically, no. However, I do know that NetSuite performs some conversions of their own on various text inputs, for example, converting all new line characters into a br tag. It's very possible that they are transforming hyperlinks into an anchor tag or some other clickable element. The best way to find out for certain is to change the setting to print to HTML instead of PDF, then compare the HTML output of the field against the original value, and see what is different. Then you can work around whatever changes Netsuite is making.
