Well, depends on what you plan to do with it.
If you were to develop it into a website / service offering other goods or services than the goods or services the trademark holder trademarked his mark for, I'd say go ahead. That would in my opinion be just about the only viable way to monetize you domainname.
Not sure how familiar you are with UDRP, but I thought it would be OK here to shed some light on the subject for others not so familiar with it.
Under paragraph 4(a) of the UDRP Policy, the registration of a domain name is considered abusive if meets all the following criteria:
(i) the domain name registered by the domain name registrant is identical or confusingly similar to a trademark or service mark in which the complainant (the person or entity bringing the complaint) has rights; and
(ii) the domain name registrant has no rights or legitimate interests in respect of the domain name in question; and
(iii) the domain name has been registered and is being used in bad faith
Boxes (i) and (iii) are quite easily ticked when you register a domainname of a standing trademark (the better known the mark, the higher the level of protection attributed).
Leaves you with box (ii). In my opinion only the option from my first paragraph fits the bill here. Some might contend parking a page with links to monetize your name would also grant you rights or a legitimate interest here. But that is defenitely not clear cut.
Moreover from a trademark law perspective ( so not UDRP, but TM litigation) this would defenitely not be considered legitimate.
