Yes, but typically not in any controlled way. Essentially you're asking whether two different encryption parameterisations map to the same ciphertext space and that is precisely what most cryptosystems do. Let's take AES-ECB as an example. Suppose that I have a key $k_0$ and a plaintext $P_0$ and a ciphertext $C=\mathrm{AES}_{\mathrm Enc}(k_0,P_0)$. Now I ...
