Hi
yes you stack them make sure the software matches , if the software doesn't match not all features will be available in the stack as the minor major numbers will be off in the versions

Major Version Number Incompatibility Among Switches



Switches with different major Cisco IOS software versions usually have different stack protocol versions. Switches with different major version numbers are incompatible and cannot exist in the same switch stack.



Minor Version Number Incompatibility Among Switches



Switches with the same major version number but with a different minor version number are considered partially compatible. When connected to a switch stack, a partially compatible switch enters version-mismatch (VM) mode and cannot join the stack as a fully functioning member. The software detects the mismatched software and tries to upgrade (or downgrade) the switch in VM mode with the switch stack image or with a tar file image from the switch stack flash memory. The software uses the automatic upgrade (auto-upgrade) and the automatic advise (auto-advise) features. For more information, see the "Understanding Auto-Upgrade and Auto-Advise" section.

They can be stacked as long as all members are running the same IOS version (and license).
