If by "frame" you mean "stack frame" then yes and yes. Virtual memory
paging is mostly language independent so the same is true for any HLL.

However, while a frame can span 2 pages, it may be difficult to
construct a frame that spans more. VM pages be made very large in
many systems (including Linux). Most modern OS configurably support a
number of page sizes from 4KB up to 1-2MB. Some 64-bit systems even
go larger.
