Would a (temporary) industry position before starting a tenure-track position have a negative effect on academic career?
Note:  I'm not addressing the ethics of taking the industry job in bad faith.  That's addressed above.

Regarding future negative impact on tenure:

No, it shouldn't have negative impact.  At least, not at a reasonable school.  But I don't know if the school you will be working at is reasonable.  I wouldn't expect this to be a negative at Georgia Tech.

The only reason it could possibly hurt is if you had zero publications during that time, and even then that shouldn't matter if it's a non-research industry job.  But even then, if you are getting interesting experience you can talk about later, that might help your research or make connections for future collaboration or funding, it's still good.

Remember, when you come up for tenure, you write your research and teaching statements, do you can contextualize this year any way you want!

Regardless, I would hope it's viewed positively. When you come up for mid-tenure review and tenure review, the committee should look at your impact (in all ways), your publications, teaching evaluations, and so on.  Generally, they want to look at the trajectory of your work since you started as a professor at this job.  Will you appear to be someone who will continue to be successful?

What you do during this gap year shouldn't impact that.  So, I would expect it wouldn't hurt in any way.

That said, I would ask the opinion of a few senior faculty at the school, and I would explain to them that you think the experience would be a good one (perhaps for informing your future work, and teaching).  That will both give you a chance to find out how senior faculty feel about this (they are the ones judging your tenure case later on) and put into their minds a positive reason for you doing this.  Looking deliberate and thoughtful about your career choices is a good thing.
