Can Frames support use cases that involve a token swap (buy token A with token B)?

Directly, no. If frame button clicks would be able to call smart contracts, then yes.

Somebody (an entity) should be able to withdraw your token, swap it on the smart contract, get the swapped token and transfer it to your farcaster wallet.

But, the problem is that no "entity" can withdraw your token for you unless you provide approval to the smart contract, by doing a transaction, which is again not possible with frame button clicks.
