Thinking out loud here:
The starmap's straight-line from Anchorpoint to Sutter's is through mostly undeveloped space.
This run is supposed to be "the Gauntlet" which could be some oblique reference to a transit through Gorgon/Shambleau or between there and Pollux - but that's not made very clear if so.
Meanwhile the Cronus is flying at .4c for 75-80 years on a vector from 26 Draconis which points somewhere, anywhere between Anchorpoint and Sutter's.
Time over distance - how far does Cronus really get?
With the two headings and that speed/time - you could probably plot the positional arc on the map where the Cronus should be given the data we have
And here's the fun... the Montero was *diverted* in transit from its base course.
This means, basically, they could change course anywhere between and "right turn" away from the base course to Sutter's and onto a new heading to intercept Cronus.
They were not dispatched straight from Anchorpoint to the Cronus - loading all of the cargo would make no sense then.
So the Montero was originally on a hauling hauling contract - and W-Y detected the Cronus inbound (somehow) and went looking for the nearest ship that could intercept.
Montero drew the short straw.
So, possible course targets like Pollux, 47 Ursa Majoris or even Groombridge 1830 are not out of the question.
