Can I easily swap out the factory boot drive with the one from my previous computer on a Legion 7 pro?

My XMG Fusion 15 recently burned out and I'm looking to get a Legion 7 Pro 5070ti as a replacement. The thing is that my data is dispersed between my 1tb boot drive and my 2tb drive, and I would like to just swap out the factory drive with my own. As this computer is coming from Lenovo and I have no idea about compatibility with the mobo firmware, I'm hesitant to pull the trigger on such a big expense, or of I should just get a different custom laptop without any storage for simplicity (and cost reduction).

Any advice would much appreciated!
