I have 2 macbook pros. Can I use one of them as an extended monitor for the other?

Apple has never supported Mac as an external monitor.

However, the Sidecar feature allows you to use a an iPad as an external monitor.

Use your iPad as a second display for your Mac with Sidecar ...

No, you can't. Target Display Mode only works on iMac.
