"svndumptool merge" is not the same thing as "svn merge". "svn merge"
merges a revision or range of revisions from a repository path into a
working copy; "svndumptool merge" merges multiple dumpfiles together,
interleaving their revisions to keep them in chronological order.
There is no such thing as a conflict with regard to what svndumptool
is doing.

How did you change repository A so that everything is under
Test_Projects? If you just used "svn mkdir" to create the
Test_Projects directory and then used "svn mv" to put Project_A and
Project_B into it, then that won't help anything; Project_A and
Project_B are still at the root of the repository in every revision
before then.

Probably what you should do is use the rename option of "svndumptool

See this example from the svndumptool README:

Moving things around

The merge command has a rename option so merge can be 'abused' to just
rename parts of a repository.

The following example shows how to add trunk tags and branches and move
everything in from the rpository root into trunk:

svndumptool.py merge -i source.svndmp -r "" trunk \
        -d trunk -d tags -d branches -m "Create trunk tags and branches." \
        -o destination.svndmp

(From http://svn.borg.ch/svndumptool/0.5.0/README.txt)

So you may want (warning: untested):

svndumptool.py merge \
-i repoA.dump \
-r "" Test_Projects \
-d Test_Projects \
-i repoB.dump \
-o combined.dump
