If you’re talking about if private keys can be extracted, YES
If you talking about the PR problem with ledger, then NO
Trezor is open source so you can see that they don’t have any code to extract the keys.
If somehow, through all the rounds of audits and security checks, the code with extraction capability makes it into production for Trezor, and without the prying eyes of this community catching it, then YES, it could very well have the „SAME PROBLEM“ of being able to extract keys
