Can ring chain isomers be positional isomers also?

I mean, the number in pcc can be same in both, but should nature of pcc have to be same in position isomers or different? (Maybe eg: from cyclopropane to propene, there is difference of fg so in this case, ring chain isomers can't be position isomers but is it always that?.. I'm confused)

Well, I haven't found any exceptions to this, but, I'm pretty sure ring chain isomers can't be positional isomers, because, in the end, the nomenclature itself is different. Positional isomerism is defined only for the same parent carbon chain, yeah.
