The short answer is yes. I have a fairly simple program that I run on both a
16F84 and various 16C5x's. The main difference I encountered is the location
of the file registers. To get around this I define my file registers in
various header files and include the appropriate one with a conditional
assembly statement.

In addition I think there is a subtle difference with the WDT and of course
the different amounts of program memory. I have an idea there are other
differences but can't think of them right now.
