Maybe but it's not best practice. I would remove and install CBU instead (assuming the rest of the structure is sufficient for tile).

I have installed tile over painted sheetrock/green/blue board when it's been for something light duty like a back splash. If is going to get any abuse I'd feel better removing the blue board and install cement board or Hardie Backer.

What kind of wall is it? Tiling over painted drywall usually isn't a big concern if it's a dry location but if it's a tub/shower surround you definitely need to replace the blue board with cement board.

It would be above the tub surround about 2 courses of tile,does'nt normally get wet.

It should be fine. Since it's probably painted with latex enamel it would be a good idea to scuff sand it first so the thinset will adhere better.
