Yes you can use 1.5mm² SWA for upto 20A if there are no derating fators to take into account, but it'd be better off on a 16A supply.
Personally I'd use 2.5mm to provide a 20A supply.

Am I missing something or is the 1.5mm SWA sold by TLC rated at 23 amps?

You're missing something.
"The Max current rating above is for XLPE insulated cables"
You can not use XPLE ratings when you are terminating into standard accesories.
Besides which you can't get a 23A circuit breaker. The next size down is 20A
i.e. a 20A supply.
I'm really beginning to think that whilst you think yu do, you really don't have enough knowledge to carry out the work you're proposing safely.

You are missing 3 things:
1) The fact that as it's XLPE cable it will have a higher capacity than PVC because it can run at 90°C.
2) The fact that you can't run it at 90°C unless everything else is rated for that temperature.
3) A great deal of knowledge which is essential if you are to DIY this. Please get an electrician.
