I have Ledger Live (Nano X) installed on my old laptop. Yesterday I received a new laptop and installed Live on that laptop. When I connected Nano X to the new laptop, after some configuration all my accounts came to the new laptop. I can see all my accounts and balances there. I even withdraw some funds from CEX to the new Live app on the new laptop. Is it safe to delete Live app from the old laptop now? Or how to make sure that I am safe and can get rid of the old laptop?

Please take an hour of your time and learn the basic mechanics of how seeds, private and public keys work on a blockchain especially in relation to Software interfaces like Ledger Live.
This lack of knowledge might make you lose your coins later down the road.

Quick digest:

You have a 12 or 24 word seed. This seed generates public and private keys.
Your ledger device connects to your PC and to your Ledger Live software.
Your ledger device provides public key upon request by Ledger Live software.
Your Ledger Live software checks the blockchain data against your public key and loads that data from the blockchain to populate your account history.

Your wallet data & history on your PC / Ledger live is only a copy from the blockchain. You can delete it at any time it doesn't have any impact on the data stored in the actual Blockchain.

Ledger Live is asking for transactions to be signed. Your Ledger device signs transactions (it never gives out your seed, it never gives out your private key).

Any time you want to restore Ledger Live on any PC/Laptop (even if for example your Laptop breaks), you can simply connect your Ledger device and it will repopulate the data from the blockchain.

Ultimately the most important part is to have your SEED WORDS SECURED.
As long as you have your 12 or 24 Seed words, your devices (Ledger, PC, Laptop) can be stolen, broken, destroyed, bricked, deleted, whatever and you will always be able to restore your access just from your seed words.

I suggest to watch the first 5 videos on that playlist: https://www.youtube.com/playlist?list=PLqyc7vcDEEqgQuKeN4F1j3thUckevmg8d
They cover the basics of how seeds words and keys work in greater detail.

On a side note. If you have only your Hardware Wallet Ledger device, without proper backups. All your coins will be lost if the device itself ever breaks or if you lose that flimsy paper that comes with it to write down your seed words.

Make 3 seed backups in steel washers (or titanium). And ideally encrypt them with a simple cipher (easiest and fastest youtube link with timestamp here
) or use a passphrase and store that separately.

Earthquake proof, Low cost, affordable, easily scalable, indestructible, fireproof 1400°C (a house fire is around 1100°C), waterproof, corrosion proof, shock proof, offline cold wallet, seed or passphrase backup.
