The way I know it is:
You cannot answer "Can/Could I use your pen?" with "Yes, you could/No, you could't".
That's according to "Grammarway 5" by Jenny Dooley and Virginia Evans (Express Publishing).
But I've just found information in "Destination C1&C2" (Macmillan) that:
For refusals, we can also use "couldn't" or "can't". "Couldn't" is more polite.
Could you give a presentation on climate change?
No, I couldn't/ can't give a presentation on climate change.
Is it really correct?
