You can play a land but you can't cast a land
In m10 they use this convention: you activate ability, cast spell and play lands
So from mtg rules


Lands

305.1. A player who has priority may play a land card from his or her hand during a main phase of his or her turn when the stack is empty.
Playing a land is a special action; it doesn’t use the stack (see rule
115). Rather, the player simply puts the land onto the battlefield.
Since the land doesn’t go on the stack, it is never a spell, and
players can’t respond to it with instants or activated abilities.
305.2. A player can normally play one land during his or her turn; however, continuous effects may increase this number.
305.2a To determine whether a player can play a land, compare the number of lands the player can play this turn with the number of lands
he or she has already played this turn (including lands played as
special actions and lands played during the resolution of spells and
abilities). If the number of lands the player can play is greater, the
play is legal.
305.2b A player can’t play a land, for any reason, if the number of lands the player can play this turn is equal to or less than the
number of lands he or she has already played this turn. Ignore any
part of an effect that instructs a player to do so.
305.3. A player can’t play a land, for any reason, if it isn’t his or her turn. Ignore any part of an effect that instructs a player to do
so.
305.4. Effects may also allow players to “put” lands onto the battlefield. This isn’t the same as “playing a land” and doesn’t count
as a land played during the current turn.

So yes, you can choose a land and you can play it.
But it counts for the maximum amount of land played during a turn, because it's say that you play the land and not put it on the battlefield
