Personally I doubt it unless there is some other reason to investigate the business activities (e.g. fraud investigation, bankruptcy proceedings, etc) but obviously it would be wise to sit down and plan what you are going to use the money for and check it is at least in the spirit of the terms (so it has to be for the business long-term interests, not to pay a big dividend, etc).
I think the main no-no is to use it to pay off other debts without prior agreement (in particular to replace debt you are personally liable for with one gov-backed). Some info was posted here:
If your company is unable to keep up with the repayments for its Bounce Back Loan, you may be worried about how this may affect your personal finances.

What you can do is use the loan to pay your salary, and income otherwise used to pay you could then buy a new van for your business (or shark with laser, as needed).
