A report exists in three states the published report definition (the rdl file), the intermediate report where any query parameters have been applied and the data pulled (this is cached in ReportServer or ReportServerTempDB databases -- depending on what type of cache), or the rendered report (such as a pdf file).
You can take a rendered report and move it elsewhere and view it provided you have the required app, acrobat reader, excel, etc.
Intermediate Reports exist in a database in a complex form so they can't really be moved.
Published reports -- well the rdl file can be moved but you can not display any data without something to process the rdl (the report server and the report server requires IIS and .NET) query the datasource and then render it.
In short -- no
