Can I use Sidecar when the iCloud accounts are different?

The iPad I am using is primarily used by my wife, thus has her AppleID signed into it. I want to use it occasionally as a second screen for my 2017 Macbook Pro, which uses my AppleID. I'd like to use Sidecar while having the main AppleID on the iPad to still be my wife's.

MacBook Pro 13″, macOS 11.4

No, both devices must be signed into the same Apple ID.

See:

Use your iPad as a second display for your Mac with Sidecar - Apple Support

Additional requirements

Both devices must be signed in to iCloud with the same Apple ID using two-factor authentication.
To use Sidecar wirelessly, both devices must be within 10 meters (30 feet) of each other and have Bluetooth, Wi-Fi, and Handoff turned on. Also make sure that the iPad is not sharing its cellular connection and the Mac is not sharing its Internet connection.
To use Sidecar over USB, make sure that your iPad is set to trust your Mac.
