If you mean loading a file into the 'local server' in the Administrative Client, then no. The server software is required, as it has the components you need -- ACIF, arsload, etc.
If your company is entitled to use CMOD, then you can install and configure a 'development' system on a local PC or an old server at no additional cost.
If you do not currently have an entitlement, but you're an IBM Business Partner, check to see if your company has purchased the Software Access Catalog, where you can download IBM software for training purposes.
