Am I right in thinking I can leave the insulation on a length of copper
wire and use that?

Yes.

Will the length I cut it at make a difference?

Yes, critical.

I mean obviously it will be longer, maybe 30" instead of 3" but does it
have to be a multiple of a wavelength or something?

Yes, but it's not quite that simple.

Connecting it to the router with low enough loss coax and the small
connectors will be the tricky bit. Far less bother to move the
wireless AP to a better location. What it's built into the same box
as the ADSL modem and that can't be moved easily. Bit stupid rarerly
is the best place for the ADSL modem the best place for a wireless
AP.

The wireless AP needs to be located away from things as much as
possible, stuffed down the back of a desk surrounded by monitors and
PC's is not, erm, ideal. You can buy aerials and TBH that is probably
the better choice as it should come with suitable cable and
connectors etc.
