Possibly. If your binary is compiled "statically", meaning it does not
draw on any external libraries, then it is likely it will work.

If it uses some shared libraries, and those libraries exist in the
target system, then there is a pretty good chance it will work.

Pick any binary you are interested, and ldd will show you what
libraries it depends on.  You could start checking versions and see.
(below I paste example)

Honestly, I've done this and the BEST thing to do is to make a source
RPM file, and compile it on both systems. THat is  a pretty easy
process, it guarantees a program will work on both.
