No, you need to find the source code and re-STORE the modules on Linux. As discussed in the SAS/IML documentation, "modules are stored in the form of their compiled code." The SAS 9.3 code on AIX will not be understandable by SAS 9.4 on Linux.
Use the SHOW STORAGE statement to find the names of the modules. Then perform a case-insensitive search for string "start <modname>" in the *.sas files. For example, if one of the modules is named MyMod, then perform a search such as
> grep -i "start mymod" *.sas
