Short answer. No, not while the occupation stays what it is. Article 540 allows only possession acquired and enjoyed in the concept of owner to serve as a title for acquiring dominion. A tenant holds in the owner's name, so his years do not accumulate towards ownership however many of them there are.

What the law says

Only the possession acquired and enjoyed in the concept of owner can serve as a title for acquiring dominion.

Quality of possession, not quantity

The common assumption is that long occupation is worth something by itself, and this article is the answer to it. Time only counts if the possession is of the right kind, and the article names both ends of it: possession must be acquired and enjoyed in the concept of owner. Acquired in that concept — you took the property claiming it as yours — and enjoyed in it since. A tenant, lessee, caretaker, overseer, borrower or relative allowed to stay fails the first requirement at the door, and nothing that happens afterwards cures it retroactively.

The thirty-year route does not rescue it either

People who learn that immovables can be acquired after thirty years without title or good faith often assume the length of stay is all that matters. It is not. Article 1137 requires that the thirty years be uninterrupted adverse possession, and adverse means precisely what Article 540 is describing: held against the owner, in the concept of owner. Occupation by permission is not adverse no matter how long it lasts, so the longer period is not an easier path for a tenant. It removes the need for good faith and just title, not the need to possess as owner.

What concept-of-owner possession looks like

It is public, and it excludes the true owner rather than coexisting with him. The occupant treats the land as his in ways others can see and the owner can hardly miss — declaring it for taxation in his own name and paying, dealing with it, mortgaging or transferring it, refusing anyone else's claim to control it, making improvements as an owner would rather than as a custodian. None of these is decisive standing alone; a caretaker may pay the tax as part of his duties. What matters is whether the whole pattern is one of claiming the land or of looking after it for somebody.

Where the answer usually lies

In the beginning of the occupation, not the end of it. Find how the family came onto the land: a lease or caretaking arrangement, a permission recorded in a letter, an old receipt, the recollection of who put whom there. Then trace the tax declarations from the earliest year available and see whose name they carry and when it changed, since an unexplained change of declarant is often the first visible sign of a claim. Those two threads, together, generally decide whether there is anything here at all.
