In theory, yes. However, if they use different providers, the
SIM might
be rejected by the other provider's phone.
If this is the case, then you can have the phone "unlocked" to accept any
provider's
SIM.

It's a loaded question given the lack of info you've given us. Again, if
the phones are from different providers, features (other than voice calls)
might not work- i.e.
SMS, web browsing, etc. without manually entering
the settings for the
SIM's provider.
Also, the frequency bands used by the phones may bedifferent.
It won't hurt anything to try- switch the SIMs, make a calll, and see how
everything works.
