So I did it. I arrived at Gare du Nord and arrived 50 minutes later at Gare Montparnasse. So it certainly is possible, but it helps to know the stations.
Thanks for the help everyone.
The Man In Seat 61 recommends allowing 70 minutes for this connection:
How long should you allow to change trains in Paris? [from Gare du Nord]
…
(3) If your onward train leaves from Paris Montparnasse
TGV station I’d also allow longer, perhaps 70 minutes or more, as
there’s quite a walk from Montparnasse metro station to the
Montparnasse TGV station.
And more details (my emphasis):
Gare du Nord ▶ Gare Montparnasse
[…] follow the signs for
Metro line M4.Take metro line M4 direct to Montparnasse Bienvenue (follow signs ‘M4
direction Mairie de Montrouge’).In contrast to other Paris mainline stations, where the metro
platforms are more or less directly underneath the mainline platforms,
at Montparnasse it’s a 700 metre (750 yard) underground walk from the
metro station to the mainline TGV platforms through broad well-lit
well-signed subways, with moving walkways for the long bits. Allow
plenty of time for the transfer, and if you’re not good with longish
walks with luggage (even with the moving walkways), consider taking a
taxi from Paris Nord to the Gare Montparnasse.
There is a direct metro line between Gare du Nord and Gare Montparnasse.
Line 4:
You get in at metro station “Gare du Nord”
You get out at metro station “Montparnasse-Bienvenüe”
According to Google, it should take about 25(ish) minutes including walking:

There will be walking between the actual train station and the metro entry at both metro stations. A metro ticket costs 1,90 euro.
By car, it is more than 30 minutes or twice that depending on the time of day (remember you are crossing Paris center, not going around).
