Yep.

The key to playing against lags when you have a marginal hand with showdown value is basically to ensure than a bet goes in on every street but to be careful not to open up the betting so that you get punished when the lag actually has a hand.

Think about the way in which Lags succeed:

1. Their aggression allows them often to push people out of pots when the lags have inferior hands and so to win a lot of pots that others normally wouldn't.

2. Their aggression and the resulting impact it has on their opponents' play allows them to generally make huge scores when they have real hands.

Now consider why lags ultimately fail:

3. Lags generally put in way too much money in situations where they don't actually have any fold equity and have inferior hands, and so tend to make a lot of hugely -EV bets.

So you basically need to play in a way that counteracts #1 and #2 and takes advantage of #3. What that basically means is to give the lag the opportunity to continue pressure-betting an inferior hand, but also not to put in huge amounts with a marginal hand yourself and pay off the lags real hand.

Lags tend to thrive in tiny pots and monster pots, either by stealing the pots that no one else has any interest in or winning monster pots those times they hit real hands and their opponents have hands as well. They tend to do quite poorly in medium-sized pots, where they neither have the advantage of taking down pots through sheer aggression nor the extra lag-value they get in big pots with real hands. So force the lag to play a medium-sized pot.
