You can do so.

But keep in mind, what is said on http://www.doepfer.de/a170.htm:

'Additional technical remarks: If the upper slew limiter is used for
precision applications (e.g. portamento/glide of one or more VCOs) a
buffer (e.g. A-185-1 oder A-185-2) is recommended between the A-170
output and the VCO(s) input(s). The reason is a small voltage drop that
is caused by the protection resistor at the A-170 output. An A-185-1 or
A-185-2 connected between the A-170 and the VCO(s) avoids that voltage
loss. For all A-170 manufactured later than May 2009 (recognizable by
the label "Version 2" on the pc board) this remark is not valid as these
modules are equipped with an additional voltage buffer at the output.
The lower slew limiter cannot be used for precision applications because
of the voltage loss caused by the diodes of the circuit.'
