Answer

Yes, it means the same. The reason is that 'Ill', as an adverb, means 'Hardly'.
So, if you put the meaning in your sentence, it'll be as, "I can hardly afford (= can't afford) to lose my job."
I hope it helps! ;)

That's exactly what it means. Nice!

Answer

I can't speak for everyone, but living in the UK, I've never heard or seen this structure.  Most people here would simply say "I can't (or cannot) afford to lose my job".
