I would say 'Yes' as it does not include any rules or variations of them. The GM is completele left on his own to do the Character creation and which rules and options he wants to use. Which is a good thing in my opinion. You are very versatile, can use Magic, Psionics, etc if you like - or skip them. Because there are no needs to use them.
If you need a character creation process and some Sci-Fi professions you could use mine from the 2300AD conversion - so you get characters with the skills needed in this adventure.
Or come up with something completely different.
The material provided in the adventure is such a lot, that you could call it a complete setting. Only missing is a history and character creation rules. Weapons, armour, equipment and vehicles, etc is provided. Nothing you need to create or provide on your own.
So, yes, you can use it as a Traveller like setting if you add these two missing parts.
Technology level it is like Star Wars and Star Trek. Space Opera, nice and easy, not too much tech everywhere, everything is reasonable. Could do Event Horizon, Pitch Black, Earth II, Pandorum, etc.
And there is a second part coming ...
Playing this Adventure will be a long campaign, nothing for three or four sessions, more like 12 to 15 and it leaves enough ideas to continue after it on your own.
