I don't think so, but you can extract the URL of a hyperlink that you hover over with the Mouse pointer. So you could hover over the hyperlink, and then use a KM Hotkey trigger to do your processing.
See:
MACRO: Create Markdown Link from Hyperlink Under Mouse [Example]
You could easily modify this macro/script to return just the URL. This should do the trick:
JavaScript to Return URL
var linkElem = document.querySelector('a:hover');
var urlStr = '';
if (linkElem) {
urlStr = linkElem.href; }
urlStr;
Replace the script in the first Execute JavaScript Action with the above script.
