Can I use a Linux laptop to connect a Mac to wifi through an Ethernet cable?

I suddenly need a wired connection for a job starting very soon but it won't be hooked up for quite some time. I have my neighborswifi password though. Iknow this is a longshot, but would I be able to use my laptop to change a wireless connection into a wired connection?

It's an older desktop Mac managed by the company. My laptop is an HP omen 15 with arch Linux on it
