Are you sure the term wasn't "integrated" rather than
"interchangeable"?
The Office applications are integrated which means you can share data
amongst the applications. You can link an Excel workbook to an Access
database and you can link Excel data in Word documents. Those are just
a couple examples, there are many many more.
Although, each application was designed for a specific purpose but
they are multifunctional too. For example you can create simple
databases in both Word and Excel, such as an address list, but if you
want the full functionality of a database then you should be using
Access which was designed for this purpose. Word can also perform
calculations but it doesn't include the ability to format numbers,
automatically recalculate, or create formulas using relative
referencing. In Excel all of this is very simple because it was
designed for this task.
The Office applications can be compared to vehicles. You can take your
car to the local home improvement store and load up a bunch of bricks
and lumber. You might be able to pull it off but if you took a truck,
which was designed to haul stuff it would be an easy task.
