The short answer is yes, with help from pstoedit.

You don't say what system you are using. I use PCB 4.1.3 on Slackware 
14.2 Linux and do this conversion to put the PCB assembly drawing into 
DXF for QCAD in order to call out the parts. Here is what I do:

 1. In PCB, select (turn on) the wanted layers. Then choose File >
    Export > EPS and select "All Layers", "Monochrome", and "Layer
    Order". Then OK to create the EPS file.
 2. Use:
    pstoedit -f dxf -xscale 1.0 -yscale 1.0 eps_file_name_from_step_1 >
    output_dxf_file_name

    Note the ">" before the output file name spec is a redirection
    character. stdout is pstoedit default output.
    Scaling can be done in QCAD, but the xscale and yscale options can
    also be used as above. This can be a script if you do this process
    often. There is also a pstoedit -rotate deg option which can be used
    to rotate the result.
    Note: using an xscale and yscale of 1.0 causes the imported block to
    be very close to the actual size in the drawing.
 3. In QCAD (or whatever you use), choose File > Import to import the
    converted image into the drawing. It will be a block, so it will not
    be editable as such, unless "exploded".

I once had a problem that not all selected layers were exported in PCB. 
I started a thread on this problem - subject= "PCB 4.1.3 png export 
acting weird​" in January of this year. Although this started applying 
to PNG output, it also applies to EPS. The workaround for this problem 
that I use is from Chad Parker dated 3:35PM 1/29/19. Note: you don't 
need a complete outline. Just a small unnoticeable line on this layer 
will suffice. Anything drawn on this layer will force the expected 
layers to produce output.

HTH.

Girvin
