Can I continue school for the PPL in another country in another flight school, if it is still inside EU?
Laws within the EU can vary, however I would assume it would be possible to carry on training in another country, however I am not sure.

The best way to know, would be to ask your flight school! :) 
They may know, and could contact the school you want to move to and work out a deal.

Best of luck

EDIT: In my country (Australia) it is possible to continue training overseas, even though we are not part of an EU style union.

EDIT 2: As I stated, if you currently undertake flight training, your instructor would know better than any online message board.
