Gaming Laptop as a Capture Card for PC?
Unlikely at all. Your laptop doesn’t seem to have an HDMI port.
You're looking for a way to stream software locally. I've noticed https://ndi.video/ mentioned before, but I haven't used it myself. Using a hardware capture device might add some extra load on the system, whereas a dedicated hardware solution could be more efficient if you need 1080p60 quality.
It's still necessary to have a capture card because video inputs aren't common in most consumer laptops. Local streaming is possible. However, unless you're an elite streamer or manage a group needing unified streams, you usually don't require more than one computer. Most current PCs handle the quality needed for mid-range or emerging streamers. People watch you, not your video clarity.
