I am growing some Autumn potatoes (Carlingford & Charlotte) and they
are just starting to sprout above ground level.

However, I have planted them right next to some tomatoes which haven't
finished cropping yet, but are starting to show quite a bit of Tomato
blight.

Is it likely that this could be transmitted to the Potatoes, or is it
a different variety that they suffer from?

If it's the same, have I left it too late already (since the tomato
blight spores must already be around) or should I dig up the tomatoes
now to give my spuds the best chance of not catching blight
themselves?

Sadly, I agree with Mike, your best bet is to remove and burn both the
tomato and the potato plants before blight further infects your soil.
Don't use the affected area to grow any of the Solanum family ( potato,
tomato, peppers, aubergine, cape goosebery etc.) for at least four
years.
